Is silicon nitride a ceramic?
Silicon nitrides are a group of advanced engineering ceramics with high strength, fracture toughness, hardness, wear resistance and good chemical and thermal stability.
Silicon Nitride Ceramic:
Silicon nitride ceramic is an inorganic material ceramic that does not shrink when sintered. Silicon nitride is very strong,especially hot pressed silicon nitride, which is one of the hardest substances in the world.
Silicon Nitride Properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
