Silicon Nitride (Si₃N₄)

Silicon Nitride (Si₃N₄) is a white to slightly beige powder that has a high melting point and good chemical stability. It is thermodynamically stable, which makes it commercially important. It has a high melting point. It shows high thermal shock resistance, high strength through a wide temperature range, high fracture toughness, high hardness, and outstanding wear resistance to abrasion and corrosion. It has a smaller thermal expansion coefficient and shows small shrinkage by reheating.
Typical Chem Analysis

Si= 59.4%
N= 38.2%

Typical Applications

Silicon Nitride (Si₃N₄) has wide applications in various kinds of fields. It is an important material for gas turbine and diesel engine parts. It is used in the manufacturing of bearings and high-heat ceramics. It is also used as an abrasive and in cutting tools. Silicon Nitride is used in electronics as an insulator and chemical barrier for integrated circuit production.
