  Ceramic grade Si3N4 powder is an important raw material of sintered Si3N4 ceramics. Silicon nitride ceramics is a kind of high temperature structural ceramics with excellent performance. It is known as the "all-round champion" in the field of ceramic materials. It not only has high strength, high temperature resistance, wear resistance, low specific gravity and other beneficial physical properties, but also can withstand the corrosion of all inorganic acids except hydrofluoric acid, with very good chemical stability.
  Hebei High-enriched Si3N4 Material Co., Ltd. selects high-purity Si powder as raw material and adopts direct nitridation high-temperature calcining process silicon. The ceramic grade Si3N4 powder prepared by the company has the advantages of high phase content, high powder purity, narrow particle size distribution and high sintering activity, and is suitable for the production of si3N4 ceramics with different processes and USES.
