  • Silicon Nitride | Ceramic Materials | Precision Ceramics

    Silicon nitride (Si 3 N 4) is a non-oxide ceramic material with a unique combination of outstanding properties.These include a high fracture toughness (5-8 MPa·m ½) in combination with a high flexural strength (800-1000 MPa) and a low coefficient of thermal expansion (3.5·10-6 K-1).This leads for example to an excellent thermal shock resistance. Furthermore, advanced ceramics are ...

  • Silicon Nitride Ceramic Air Heating Element (Si3N4)

    Silicon nitride components may be produced in dense form from a powder through the conventional sintering or hot-pressing routes. An interesting and important feature of the material, however, is that lower density (2300–2700 kgm –3) components may be produced directly by the nitridation of compacted silicon powder—the reaction-bonding (or reaction-sintering) route.
