Ready to press silicon carbide powder 120um

Ready to press silicon carbide powder 120um (RTP silicon carbide powder) is made of high-purity submicron silicon carbide powder as raw material, with binder added, and through spray granulation technology. It has the characteristics of uniform particles, low forming pressure, and low sintering temperature. The pressureless sintered silicon carbide ceramics produced from RTP silicon carbide granulation powder have the advantages 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.
