Being made with the mixture of fine particles α-SiC and additives, the granulation powder is pressed into blank. The carbon within the blank contacted with free silicon in a vacuum sintering furnace at 1500℃ and reacts with the infiltrated Si and then becomes β-SiC which form the high-density silicon carbide material along with α-SiC.
Reaction Bonded Silicon Carbide has characteristics of high hardness, strong wear resistance, good self lubrication, low friction coefficient, high temperature resistance, high thermal conductivity, etc.
It's suitable for general working conditions, restricted being used in hydrofluoric acid and strong alkali conditions due to free silicon contained in reaction bonded silicon carbide.
Mechanical seal, pump, bearing, petroleum, chemical industry, automobile, ships, power, pharmaceutical industry, new energy, etc.
