Silicone material - Import export

Silicon nitride is one of the hardest ceramics but also one of the most resistant. Si3N4 is mainly used in severe environments which combine extreme temperatures with abrasive and/or corrosive medium. Silicon nitride can be of different grades : sintered, hot pressed or reaction bonded. Selection of materials Microcertec offers two high-purity Si3N4 grades that are particularly suited for hostile environments : sintered silicon nitride hot pressed silicon nitride Both Si3N4 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 Si3N4 grades offer a low thermal expansion. Properties Sintered silicon nitride and HP Si3N4 have the following properties : low density excellent thermal shock resistance excellent wear resistance excellent corrosion resistance (liquids and gas) low coefficient of thermal...

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...
