Product Features and Uses
Pressureless sintered silicon carbide sealing rings have excellent thermal conductivity, outstanding thermal shock stability, better wear resistance, high temperature resistance, and chemical corrosion resistance, and can be used at high temperatures of 1600℃, suitable for mid to high-end mechanical seals.
Characteristics of Pressureless Sintered Silicon Carbide Ceramics
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 sealing rings, flat rings, sandblasting nozzles, bulletproof plates, ceramic heating plates, ceramic heat distribution plates, 3D glass thermal bending grinding tools, microchannel reactor ceramic plates.
Products from JNDE NEW MATERIAL Company made of silicon carbide ceramics have characteristics such as 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, and 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.
