  • Silicon Nitride (Si3N4) Properties and Applications

    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 ...

  • Manufactures of Silicon Nitride Technical ceramics |

    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.

    2020-1-1 · Silicon nitride has the ability to develop a passivating layer on the surface when it reacts with the environment (dry or moist). The bulk of Si 3 N 4 is purely Si–N, while it transits from that phase to Si–N–O in the middle and pure Si–O surface at the surface due to passivation. Hence, the surface chemistry of silicon nitride reveals the composition of charged SiNH 3 +, SiOH 2 +, SiO ...
