Silicon Nitride (Si₃N₄) Products: Silicon nitride (Si₃N₄) products are high-performance materials with outstanding properties. They feature high mechanical strength that remains stable at elevated temperatures, a low coefficient of friction with self-lubricating characteristics, and a low thermal expansion coefficient with excellent thermal shock resistance, enabling long-term use at 1400–1850°C. They also exhibit strong resistance to most acids and alkalis, providing excellent chemical stability. In addition, they offer excellent electrical insulation at room temperature, with high resistivity and stable dielectric properties.
Electronics Industry: Used in the manufacture of circuit substrates, thin-film capacitors, and high-temperature / thermal cycling electrical insulators.
Chemical Industry: Applied in the production of ball valves, sealing rings, filters, heat exchanger components, catalyst supports, and combustion boats.
Aerospace Industry: Used in thermal protection systems and engine components of aircraft, ensuring stable performance under extreme operating conditions.
Mechanical Engineering: Applied in high-speed cutting tools, bearings, heat treatment supports, engine scraper rings, and gas turbine blades.
