Product Features and Uses
This product has good high-temperature oxidation resistance, high hardness, high thermal conductivity, and no deformation at high temperatures. Based on these excellent properties, it can completely replace the currently used high-temperature stainless steel, various alloy heating plates, and expensive imported foreign ceramic heating plates.
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. They are sintered in an inert gas or vacuum atmosphere at high temperatures of 1950-2100℃ under atmospheric pressure, resulting in products that 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, and ceramic plates for microchannel reactors.
The silicon carbide ceramic products from JNDE NEW MATERIAL Company 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. 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.
