Product Features and Uses
Compared to metal materials, silicon carbide valves have excellent high-temperature mechanical properties, chemical corrosion resistance, high-temperature oxidation resistance, wear resistance, and low specific gravity.
Characteristics of Pressureless Sintered Silicon Carbide Ceramic Materials
Pressureless sintered silicon carbide ceramics are made from high-purity, ultra-fine silicon carbide powder, with a small amount of sintering aids added, sintered in an inert gas or vacuum atmosphere at high temperatures of 1950-2100℃. The resulting products are almost completely dense and have excellent mechanical properties. Pressureless sintered silicon carbide ceramics include: shaft sleeve products, sliding bearing products, mechanical seal rings, flat rings, sandblasting nozzles, bulletproof plates, ceramic heating plates, ceramic heat distribution plates, 3D glass thermal bending grinding tools, and microchannel reactor ceramic plates.
Products made from silicon carbide ceramics by JNDE NEW MATERIAL Company feature acid and alkali corrosion resistance, high hardness and wear resistance, good self-lubrication, high-temperature oxidation resistance, low thermal expansion coefficient, and good thermal conductivity. They are widely used in aerospace, automotive industry, petrochemical, mechanical seals, metallurgy and power, pump equipment, thermal bending grinding tools, microchannel reactors, new energy, semiconductors, scientific research, and national defense military industries.
