Black silicon carbide for carbon ceramic brake disc
Carbon ceramic brake disc is a kind of brake disc made of carbon fiber reinforced black silicon carbide powder composite material. The main components of the carbon ceramic brake disc matrix are black SiC powder, silicon (Si) and graphite. The role of carbon fiber provide the mechanical strength and fracture toughness required for the material, while the silicon carbide in the matrix determines the hardness of the composite material, and silicon and graphite improve the friction coefficient of the brake disc.
Black silicon carbide is made from silica sand and smokeless acetylene. It is made via light resistance from hydrometallurgical, it is black opaque body hexagonal crystal and MOHS -hardness in the 9.15, its hardness just less than diamond and boron carbide, crisp and sharp performance and certain degree of conductive heat. It’s toughness is higher than green silicon carbide, it’s SiC purity 98.5%, it have been used for processing glass,ceramic,stone, refractory materials , ceramic product, cast iron and other metal.
