설명

일반 설명

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.
