SIC Ceramic Pressureless Sintering Production Process

Silicon carbide ceramics have stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance. In addition to being used as abrasives, there are many other uses, such as: coating silicon carbide powder on water turbine impellers or cylinder blocks with special processes The inner wall can improve its wear resistance and prolong its service life by 1^ 2 times; the high-grade refractory material made of it is heat-resistant, small in size, light in weight and high in strength, and has a good energy saving effect. Low-grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer. It can speed up the steelmaking speed, and facilitate the control of chemical composition and improve the quality of steel.

Pressureless sintered silicon carbide (SiC) ceramic is a new type of bulletproof ceramic material. The ceramic material has excellent properties such as low density, high strength, high hardness, high temperature resistance, oxidation resistance, and corrosion resistance. It is currently manufactured It is the general material of choice for discs, mechanical seals, sandblasting nozzles and magnetic pump canned motor pump components. It is mainly used for high thermal conductivity, abrasion resistance, fire resistance, bullet resistance, heat resistance, high temperature resistance, no deformation, no cracking and no slagging.
