Black sic powder to make carbon ceramic brake disc
Carbon ceramic brake disc is a kind of brake disc made of carbon fiber reinforced silicon carbide composite material. The main components of the carbon ceramic brake disc matrix are silicon carbide (SiC), silicon (Si) and graphite. The role of carbon fiber is to provide the mechanical strength and fracture toughness required by 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. Carbon ceramic brake disc is a new type of brake material developed in recent years. It has the advantages of low density, high temperature resistance, high and stable friction performance, etc. It has a wide range of application prospects in high-energy braking fields such as automobiles, high-speed trains, and aircraft.
Black sic powder 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.
