Maideli is a professional company of design ,production and sales for precious ceramics ,refractory ceramics and new inorganic non-metallic materials ,that is alumina ,zirconia ,magnesia ,silicon nitride and silicon carbide .
Product details
Silicon Nitride (Si3N4) ceramic is high purity silicon nitride as raw materials,using pressure sintering process . Products with high temperatue ,wear (and with self-lubricating) ,high hardness ,high strength ,high insulation properties,the strength of the product has been able to maintain the high temperature of 1200 ℃ without falling until 1900 ℃ will be decomposed, oxidation can also work to 1400℃,and has amzing chemical resistance ,resistance to almost all inorganic acide corrosion . Therefore ,it can be widely used in the high temperature ,strong acid ,alkali and corrosive environment .
