Silicon carbide - Import export

Silicon carbide can be made in different chemical compositions. It can be found either as lower purity grades mostly used for thermal applications or high-purity grades (sintered SiC and CVD SiC) that makes silicon carbide an advanced ceramic with exceptionnal mechanical and thermal properties. Selection of materials Microcertec offers two high-purity silicon carbide grades that are particularly suited for hostile environments : sintered silicon carbide CVD silicon carbide Both SiC materials are mainly designed to be used in thermal-mechanical or corrosion-resistance applications because they show an outstanding behaviour to resist to wear, thermal shocks and corrosion (liquids and gases). Moreover, these pure SiC grades offer a high thermal conductivity, in the range of 120 to 160 W/m.K for sintered silicon carbide and 250 W/m.K for CVD SiC. Properties Sintered silicon carbide and CVC SiC have the following properties : low density excellent thermal shock...
