Silicon nitride ceramic seal ring
Silicon nitride ceramic seal ring for fluid equipment, with high strength, wear resistance, corrosion resistance.
Silicon Nitride Ceramic Insulating Ring
Used in polycrystalline silicon reduction furnace electrode insulating rings instead of alumina ceramic; with resistance to higher temperatures and bigger strength, far better stability of thermal shock resistance than alumina ceramic, the service life is more than ten times extended, so the production cost is largely reduced, the operation time is saved and the labor intensity is reduced accordingly.
