Silocon carbide have the property of excellent resistant-corrosion, high mechanical strength, high thermal conductivity,good self-lubrication, used as seal faces, bearings and tubes in spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, pharmaceutical, auto industry and so on. When the sic faces are combined with graphitefaces the friction is the smallest and they can be made into mechanical seals which are able to work in highest working requirements.
· Reaction
Bonded Silicon Carbide (RB SiC) - a very economical
material which gives excellent wear characteristics, as
well as good chemical resistance.
· Sintered Silicon Carbide (SSiC) - the absence of free silicon makes it most resistant to chemically-aggressive fluids, and ideal for high temperature applications.
