Silicon nitride powder is a high-performance ceramic raw material, primarily mixed hexagonal α-Si₃N₄ and β-Si₃N₄ crystal powder, categorized into micron-grade (particle size 1–10 μm) and nano-grade (particle size ≤100 nm). Mainly synthesized via nitridation reaction of silicon powder and nitrogen, it features outstanding high-temperature resistance, high strength, high hardness and corrosion resistance, serving as the core raw material for high-end structural and functional ceramics, widely applied in new energy, electronics, aerospace and automotive industries. Classified by purity: industrial grade (purity ≥98%), high-end electronics grade (purity ≥99.5%, low impurity content), aerospace grade (purity ≥99.9%, high densification). Industrial grade accounts for over 65% of market volume as the mainstream product category.
