Silicon Nitride Insulating Ceramic Silicon Nitride Insulating Ring
Product Overview
Silicon nitride ceramics have high strength, especially high-purity
silicon nitride, which is one of the hardest substances in the
world.
Very strong corrosion resistance, can be used in strong acids and alkalis, soluble in hydrofluoric acid but does not react with other organic acids
