Pressureless silicon carbide is a sintered product with excellent characteristics such as high purity, fine crystal and extremely low porosity. It can be used as a substitute for graphite, stainless steel, Hastelloy alloy and fluoroplastics in the environment of high temperature, high pressure, strong corrosion and high wear in chemical industry, medicine, metallurgy, etc
Pressureless sintered silicon carbide is a new technology product. Compared with reaction sintered silicon carbide products, pressureless sintered silicon carbide has more perfect crystal structure, better corrosion resistance and wear resistance due to different formation processes
The product has smoother surface, higher density and higher strength. It is a product naturally shrunk below 2100 ℃
The product is made of high-purity and ultra-fine silicon carbide powder as raw material, with a small amount of sintering additives, such as boron and carbon, sintered at 1950-2100 high temperature in atmospheric pressure inert gas or vacuum atmosphere. The product is almost completely compact and has excellent mechanical properties.
