Product Features and Uses
Silicon carbide crucibles are ceramic deep-bottomed bowl-shaped containers. When there are solids to be heated with a high flame, a crucible must be used. Because it can withstand high temperatures better than glassware.
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: 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, and microchannel reactor ceramic plates.
Products from JNDE NEW MATERIAL Company made of silicon carbide ceramics have characteristics such as resistance to acid and alkali corrosion, 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 sealing, metallurgy and power, pump equipment, thermal bending grinding tools, microchannel reactors, new energy, semiconductors, scientific research, and national defense military industries.
