Our large-size silicon nitride ceramic ball is used in the insulation bearings of wind driven generator, breaking the international technology blockade and monopoly. It makes the price of the product reduce by nearly 50% and accelerates the localization of key components of high-power grid-connected wind-driven generators.

The silicon nitride insulating ring, thermal shield, and insulating sleeve that we developed have been widely used in polycrystalline silicon reducing furnaces and other fields.They are not only resistant to high temperatures, but also can reduce the replacement frequency, enjoy longer service life, and save costs, which highlights the unique value of advanced ceramic in the area of energy environment.
