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...
