1. Imbalanced aluminum-boron ratio and excessive free elemental substances: Excessive free aluminum precipitates pores during high-temperature melting; excess free boron causes brittle cracking of the aluminum matrix and drastically reduces composite material strength. Unqualified component ratios lead to failed grain refinement of molten aluminum.
2. Elevated total oxygen generates impurity phases of aluminum oxide and boron oxide, causing coating blistering and peeling under high-temperature operating conditions and drastically shortening mold wear resistance service life.
3. Excessive iron, silicon and other heavy metals violate RoHS regulations, resulting in direct rejection of raw materials for aerospace and electronic applications.
4. Severe powder agglomeration and inconsistent particle size distribution lead to uneven mixing and dispersion, forming pores and delamination in molded parts and lowering finished product yield.
1. High-temperature solid-phase synthesis with precise control of feed ratios; free aluminum and free boron controlled within 50% of regulatory limits to deliver stable batch-to-batch grain refinement performance.
2. Deoxidation refining under inert high-temperature atmosphere; total oxygen indicators exceed access standards for high-end composite materials to prevent coating peeling and flaking under high temperatures.
3. Multi-stage impurity removal via pickling and magnetic separation; harmful heavy metals meet European and American aerospace and electronic environmental access requirements.
4. Powder deagglomeration via air flow and classified screening to achieve narrow particle size distribution with excellent powder dispersibility, enabling dense molding without pores after batching.
1. Fluctuating grain refinement activity; inconsistent grain size across aluminum castings from the same batch, leading to uneven mechanical properties.
2. Prone to moisture absorption, oxidation and agglomeration during storage, causing feeding blockages; localized agglomeration of refiners triggers partial defects in castings.
3. Continuous oxygen absorption under low-temperature and high-humidity storage environments elevates oxygen content and causes premature product performance degradation.
1. Stable specific surface area maintained via consistent synthesis processes; batch activity fluctuation ≤0.4% to deliver uniform and stable grain structure in castings.
2. Inert surface coating treatment of powder plus high-barrier sealed packaging to resist moisture absorption and caking under conventional storage conditions.
3. Pre-treatment via vacuum dehydration and closed low-temperature storage to limit oxygen content increase during long-term storage.
1. Heavy metals and soluble impurities approach control thresholds set by Japan’s Ministry of Health, Labour and Welfare; failed customs sampling inspections prevent local production.
2. Absence of Japanese raw material filing documents blocks access to supply chains of leading Japanese automakers and precision ceramic manufacturers, limiting product premium potential.
3. Unstable oxygen content causes fluctuations in thermal conductivity of ceramics, leading to returns and compensation claims from terminal component manufacturers.
1. Secondary high-temperature purification and impurity removal; restricted harmful impurities reduced to below 40% of Japanese national standards for smooth customs clearance inspection in Japan.
2. Supporting Japanese MSDS and full-item COA test reports; assistance with Japanese chemical raw material import filing.
3. Strict control of total oxygen parameters to stabilize physicochemical properties of thermal conductive ceramics and match formulation requirements of Japanese precision components.
1. Low-end raw materials adulterated with aluminum powder, silicon carbide and graphite; insufficient effective aluminum diboride content leads to failed grain refinement and scrapped castings with pores.
2. High-temperature and high-humidity tropical environments accelerate moisture absorption, oxidation and agglomeration; simple woven bag packaging causes high material loss; incomplete documentation leads to customs detention and fines.
1. Economical industrial grade without filler adulteration, stable physicochemical indicators, priced 22%~27% lower than premium aerospace grade.
2. Double-layer moisture-proof sealing with PE inner film + woven bags; resistance to moisture absorption, agglomeration and oxidation for 3 months under 45°C high-humidity conditions.
3. Batch-specific COA, MSDS and Halal certificates provided; support for import declaration to reduce detention risks.
1. Counterfeiting via adulteration with aluminum powder and low-cost carbon powder with falsely labeled purity; mass scrapping of aluminum casting products and major compensation losses damaging downstream client relationships.
2. Breathable packaging causes moisture absorption and oxidation, leading to full order rejection by high-end composite material manufacturers; incomplete qualifications block access to leading European and American procurement chains.
3. Open repackaging absorbs atmospheric moisture; oxygen content rises during small-package storage and grain refinement performance deteriorates.
1. Direct supply from original synthesis manufacturers; batch-specific full-item COA covering elemental ratio, oxygen content and impurities, supporting third-party SGS re-inspection with zero adulteration guarantee.
2. Aluminum plastic vacuum lining + thickened fiber drum sealing to isolate oxygen and moisture for ocean shipping under variable temperature conditions.
3. Repackaging under inert closed environments; physicochemical indicators remain stable without obvious degradation after 12 months of cool storage at 25°C. One-stop provision of full compliance qualifications including REACH, RoHS and Japanese & South Korean import documentation.
If you require more professional and in-depth analysis regarding Aluminum diboride selection, please contact HiSiaddi customer service.
Raw material powder was prone to moisture absorption and caking. Hard caking appeared after the powder was stored in ordinary warehouses for one month, making normal sieving impossible. Caked particles led to uneven material mixing.
Foaming and internal cavities formed during composite material processing. Moisture and volatile impurities carried by the powder vaporized during high-temperature extrusion and vulcanization, forming a large number of bubbles that remained as cavities after cooling and damaged the thermal conductive structure.
Continuous attenuation of thermal conductivity. After being stored for 15 days, the thermal conductivity of finished thermal conductive plastics and adhesives decreased by more than 14%, failing to maintain stable long-term performance.
Blistering and delamination after long-term use. Trace moisture and reactive gas gradually accumulated inside composite materials, causing surface blistering and interface delamination after 1 to 2 months of service, which rendered the products completely unusable.
Poor compatibility between powder and polymer matrix resulted in uneven dispersion. The thermal conductivity varied in different areas of finished products, leading to unstable quality among batches.

Classification: Inorganic boride ceramic powder, metallurgical grain refiner, composite filler raw material; Key controlled indicators: Al/B ratio, free aluminum, free boron, total oxygen, residual carbon, Fe/Si/Ca impurities, particle size distribution
· EU: REACH substance registration; electronic fillers subject to RoHS heavy metal control; metallurgical additives comply with REACH impurity control standards
· North America: TSCA inventory listing; aluminum processing materials follow ASTM inorganic powder specifications
· Japan & South Korea: Chemical Substances Control Law raw material filing; mandatory control of free elemental substances and oxygen content for aluminum alloy grain refiners
· Southeast Asia / Middle East: General metallurgical raw material standards; orders shipped to Europe and America must be accompanied by batch-specific COA, full-item SGS test reports and raw material traceability documents. Customs will focus on reviewing impurity reports; shipments with excessive oxygen content or free elemental substances are prone to customs detention and inspection.
Properties: Silver-gray powder with metallic luster, insoluble in water, resistant to molten aluminum corrosion, combining metallic conductivity and ceramic wear resistance.
1. Aluminum-boron stoichiometric ratio (Al:B ≈ 1:2): Imbalanced ratio generates large amounts of elemental Al/B, resulting in failed grain refinement, increased sintering pores; a core indicator for aluminum metallurgy.
2. Free aluminum + free boron: Elemental impurities that cause pores and component segregation in finished products when added to high-temperature molten aluminum; rigidly controlled for high-end aluminum grain refiners.
3. Total oxygen content: Oxide impurities including surface Al₂O₃ and B₂O₃; excessive oxygen drastically reduces grain refinement efficiency and weakens interfacial bonding of composite materials.
4. Residual carbon: Synthetic by-product impurity; carbon inclusions damage the compactness of aluminum alloys.
5. D50 median particle size: 0.5~2μm for electronic fillers; 3~8μm for aluminum grain refinement; 10~35μm for wear-resistant spraying. Particle size directly affects dispersibility and refinement performance.
6. Compatibility characteristics: Blended with aluminum powder, silicon carbide and titanium diboride to prepare multi-phase wear-resistant materials; directly added into molten aluminum for grain refinement. Small-scale melt tests and metallographic observation of grain effects are recommended for new formulations.
1. High-purity electronic / premium aluminum grain refiner grade (precision aluminum alloys and electronic composite fillers for Europe, America and Japan): AlB₂ ≥99.0%, total oxygen ≤0.9%, free Al ≤0.3%, free B ≤0.25%, residual carbon ≤0.2%, D50=0.8~2μm, Fe+Si+Ca ≤120ppm
2. General aluminum processing grain refiner grade (die-cast aluminum and section aluminum refining): AlB₂ ≥97.5%, total oxygen ≤1.8%, total free elemental substances ≤0.9%, D50=3~7μm
3. Industrial wear-resistant spraying grade: AlB₂ ≥94.0%, relaxed standards for oxygen and impurities, coarse particle powder
Core technological process: High-temperature solid-phase synthesis / aluminothermic smelting of aluminum powder + boron powder → crushing and grinding → pickling for impurity removal → drying under inert atmosphere → air classification. Key control points: precise elemental ratio control in solid-phase synthesis, inert atmosphere to suppress surface oxidation, pickling to remove metallic impurities, accurate particle size screening. Integrated manufacturers with self-owned synthesis and purification lines are preferred, equipped with complete ISO9001 quality inspection systems. Large manufacturers deliver stable batch consistency of composition and oxygen content, and can issue cross-border test reports from SGS, Eurofins, etc. Packaging: 25kg aluminum foil vacuum-lined fiber drums, bulk bags; lead time 8~15 days. Small manufacturers adopt extensive synthesis processes with excessive free aluminum, boron and oxygen, unable to fulfill high-end aluminum processing export orders.
Physicochemical properties: Chemically stable at room temperature, non-hazardous chemical; ultra-fine powder easily absorbs moisture and undergoes surface oxidation.

5. Residual carbon: ≤0.20% for premium grade; ≤0.55% for general grade; ≤1.40% for industrial grade
6. Median D50: 0.5~2μm for electronic filling; 3~8μm for aluminum grain refinement; 10~35μm for spraying
7. Appearance: Uniform silver-gray powder without agglomerates or foreign colored particles; agglomeration indicates moisture-induced oxidation.
Strict control of total oxygen, free elemental substances and trace metallic impurities to comply with RoHS; ensure uniform grain refinement of molten aluminum and dense composite materials free of inclusions.
Control main content and free impurities to stabilize grain refinement performance and reduce pinhole defects in aluminum parts.
Prioritize particle size and main content with focus on procurement cost control.
Basic documents: Batch-specific COA, Chinese-English MSDS, full-item SGS test reports (purity + total oxygen + free Al/B + impurities + particle size); EU: REACH registration documents; North America: TSCA filing; Japan & South Korea: chemical substance declaration materials; value-added qualification: RoHS test report (for electronic material orders).
1. Moisture absorption triggers surface oxidation and elevates total oxygen content; vacuum sealing is the core control measure for ocean shipping.
