  • Silicon Nitride Ceramics - Syalons

    2019-12-16 · Silicon nitride was discovered in the mid-nineteenth century but did not lend itself to ease of fabrication, due to its covalently bonded nature. This initially led to the development of two types of silicon nitride, reaction-bonded silicon nitride (RBSN) and hot pressed silicon nitride (HPSN). Subsequently, since the 1970s two further types ...

  • Silicon Nitride (Si3N4) Properties and Applications

    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.
