Silicon nitride photovoltaic structural parts (silicon nitride ceramics for polysilicon reduction furnace)
The polysilicon reduction furnace is a special equipment for refining polysilicon rods. The high-voltage start-up method requires high-voltage breakdown first, so that pure silicon becomes a conductor with lower resistivity, thereby increasing the on-current speed, making the internal temperature of the silicon core rise rapidly, and greatly shortening the start-up time. time and improve production efficiency. Therefore, high-temperature-resistant high-insulation ceramic materials are required to prevent insulation failure under high temperature and high pressure, resulting in electrical breakdown. Alumina has a very short service life due to its own performance limitations, so silicon nitride ceramic materials become a substitute.
Taisheng's silicon nitride insulator is produced by cold isostatic pressing,atmosphere sintering,high temperature stress relief treatment and precision machining process. The product has excellent performance, stability and reliability. We can also produce various structural parts for photovoltaic industry according to customer's drawing requirements.
