Introduction
The pressureless sintered silicon carbide ceramic granulation powder has reasonable particle gradation, uniform green body density, good forming performance, high bulk density and good flow performance. The pressureless sintered silicon carbide ceramics produced by it have the characteristics of high strength, high hardness, wear resistance, acid and alkali corrosion resistance, and good thermal conductivity, and are widely used in bulletproof, chemical, mechanical and other fields.
