METHOD OF MANUFACTURING SILICON CARBIDE FINE PARTICLES-DISPERSED CERAMIC SINTERED COMPACT

PROBLEM TO BE SOLVED: To provide an inexpensive method of manufacturing a silicon carbide fine particle-dispersed ceramic sintered compact having a high density and a high strength. SOLUTION: The method of manufacturing the silicon carbide fine particle-dispersed ceramic sintered compact is characterized by using a pot and /or balls for pulverization which is composed of a ceramic material containing 50% to 99% silicon carbide by volume ratio, charging ceramic powder except silicon carbide and the balls into the pot, wearing the balls themselves for pulverizing and/or the inside surface of the pot in a process for pulverizing and mixing the ceramic powder by rotating or vibrating to incorporate ≥0.5vol.% to ≤4vol.% silicon carbide having ≥0.02 μm to ≤0.2 μm average particle diameter in the ceramic powder, and firing after molding the resultant ceramic powder.
