Particularly it is suitable for using in such cases to be required with no any leakage as working condition of feeding strong ac   Sealing RingHot pressure sintered boron carbide ceramic sealing ring has such advantages as high compact density, high hardness, strong corrosion resistance, excellent wearing quality, small friction coefficient, oxidation resistance, small creeping bentgrass at high temperature, good thermal stability, so it is widely applicable to feeding pump with liquid contained large numbers of solid granule and liquid with strong causticity. Particularly it is suitable for using in such cases to be required with no any leakage as working condition of feeding strong acid, strong alkali and causticity liquid. Semiconductor and Thermoelectric CellBoron carbide ceramic can be used as high temperature semiconductor component, also as gas distribution tray, focus ring, microwave or infrared ray window, DC plug, high temperature thermocouple element, radiation hardening thermoelectric cell in semiconductor industry.
