Application

Silicon Nitride Nanofiber, appearing as a slightly beige powder, serves a crucial role in the preparation of thermally conductive Poly(Me Methacrylate)/Silicon Nitride nanocomposites through click chemistry. Composed of silicon and nitrogen (Si3N4), this compound is known for its impressive properties, such as high strength over a wide temperature range, excellent fracture toughness, remarkable hardness, and outstanding wear resistance. Its high thermal shock resistance makes it valuable in various applications across multiple industries. In the automotive field, it is an essential material for engine components, while its shock resistance makes it suitable for bearing production. Its capacity to withstand severe thermal shock is advantageous in aerospace, particularly in the harsh conditions of hydrogen/oxygen rocket engines. Additionally, Silicon Nitride is utilized as an abrasive and in cutting tools because of its hardness and wear resistance. Within the electronics sector, it functions as an insulator and a chemical barrier in integrated circuit production. The production of Silicon Nitride can be achieved through several methods, including nitrogen heating of powdered silicon, the diimide route involving SiCl and NH3, and carbothermal reduction of silicon dioxide in the presence of nitrogen.
