General description

Silicon nitride based ceramics possess high fracture toughness, hardness and wear resistance, resistance to corrosion, thermal stability. Two known polymorphs of silicon nitride exist, alpha and beta Si3N4, both have hexagonal structure. A study shows that a third state, cubic spinel structure, has also been synthesized.
