Silicon nitride ceramic, high voltage insulating ring sheath

Detailed introduction
Detailed information: Pingxiang Ruize Silicon Ceramics Co., Ltd. provides high-quality silicon nitride ceramics, alumina ceramics, alumina ceramics, high-voltage insulating ring sheaths (monocrystalline silicon, polycrystalline silicon, reduced Furnace and hydrogenation furnace high-voltage insulating ring sheath, heat shield) are special new material products (monocrystalline silicon, polycrystalline silicon projects). () Silicon nitride ceramic The silicon nitride ceramic ring has good insulation, high toughness, high temperature resistance and good shock resistance, which can extend its service life. The added sintering agent helps to densify and can meet the environmental requirements of polysilicon reduction furnaces. requirements, long service life and improved work efficiency.
