Silicon Nitride
Silicon nitride, a covalent-bonded ceramic material, is known for its ultrahigh strength, extreme temperature resistance (~1900°C), low density, and exceptional chemical stability. It also features superior thermal shock resistance, preventing cracks under rapid temperature changes, along with excellent wear and oxidation resistance. These properties allow it to maintain structural integrity in harsh environments, including ultrahigh temperatures, corrosive media such as molten metals and acidic solutions, and high-speed mechanical impacts. Its durability and reliability make it indispensable for aerospace engine components, precision ceramic bearings, semiconductor etching equipment, and biomedical implants.
Recognized as a “cutting-edge structural ceramic,” silicon nitride also plays a crucial role in high-temperature industrial processes, renewable energy technologies, and advanced equipment manufacturing. Its unique combination of mechanical strength, thermal stability, and chemical resistance enables innovation across various industries, supporting the development of more efficient and durable high-performance systems.
