Product Features and Uses
Due to its high content of silicon carbide, high density, high hardness, and high wear resistance, it is widely used in different types of ceramics, glazes, glass, and the precision grinding and cutting of hard materials in chemical plants.
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. They are sintered in an inert gas or vacuum atmosphere at high temperatures of 1950~2100℃, resulting in products that are almost completely dense and possess excellent mechanical properties. Pressureless sintered silicon carbide ceramics include: 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 ceramic plates for microchannel reactors.
Products from 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 tools, microchannel reactors, new energy, semiconductors, scientific research, and national defense military industries.
