  • Paper derived SiC–Si3N4 ceramics for high

    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.
