Title: Production of silicon nitride powder
Inventor: MIYAZAWA HIDENOBU
IPC: C01B21/068
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To considerably reduce the amt. of unreacted metallic Si in silicon nitride powder by compacting powdery stock contg. metallic Si so that pores each having below a specified diameter account for a specified percentage and carrying out nitriding by heating in a nitrogen-contg. atmosphere. SOLUTION: Powdery stock contg. metallic Si is compacted so that pores each having >=1μm pore diameter account for <30vol.% of the total pore volume and then nitriding is carried out. Since the pores in the resultant metallic Si compact act as passages for atmospheric gas at the time of nitriding, the pores are open pores having openings in the surface of the compact. When pores each having <=1μm pore diameter account for >=30vol.% of the total pore volume, metallic Si is sintered before satisfactory nitriding to make the pores closed, the penetration of gaseous nitrogen into the compact is blocked and unreacted metallic Si remains in produced silicon nitride.
