  • 4 Types of Silicon Nitride Ceramics | Advanced

    Silicon Nitride Ceramics. Silicon nitrides (Si 3 N 4) are a range of advanced engineering ceramics characterised by high strength, toughness and hardness and excellent chemical and thermal stability.. Silicon nitride was discovered in the mid-nineteenth century but did not lend itself to ease of fabrication, due to its covalently bonded nature.
