High Precise Silicon nitride parts Silicon Nitride (Si3N4) ceramic fork

Silicon Nitride (Si3N4) is an advanced ceramic material with a high melting point, very high hardness and chemical inertness, and excellent thermal shock resistance. It is often used to manufacture mechanical components such as bearings, gas turbine blades, mechanical sealing rings and permanent moulds.

Silicon Nitride (Si3N4) is widely recognized for its exceptional mechanical, thermal, and electrical properties, making it a top choice for advanced ceramic applications. With its remarkable hardness and outstanding thermal shock and impact resistance, Silicon Nitride outperforms many metals in high-temperature environments. Its unique combination of creep and oxidation resistance, coupled with low thermal conductivity and high wear resistance, positions it as a superior material for demanding industrial settings. When faced with extreme conditions requiring high-temperature and high-load capabilities, Silicon Nitride stands out as a reliable and durable option for a wide range of industrial applications.
