Silicon Nitride Wear - Resistant Ceramic Fitting Insulation Ring
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.
The product has the advantages of high density and uniformity, excellent thermal shock resistance, corrosion resistance, high temperature resistance, pollution-free, high insulation, and is not affected by a reducing atmosphere. It has a long service life and is especially suitable for harsh conditions such as hydrogen reduction furnaces. Electrode protection. Can be processed according to customer demand specifications.
