Огнеупорные нитрида кремния керамического порошка

Silicon Ntride ( Si3N4) is a kind of important structural ceramic which has the characteristics of high hardness, self-lubrication and abrasion resistance. It is atom crystal and doesn’t arise reaction to other inorganic acids except for hydrofluoric acid. Silicon Nitride Ceramic Powder is well resistant to corrosion and oxidation while high temperature. It also can excellently resist the thermal shock and will not be cracked after the sudden rising and falling of temperature when silicon nitride was heated to above 1000°C in the air.Silicon Ntride ceramic is widely used to manufacture bearing,turbine blade, mechanical seal ring, permanent mold and other mechanical parts. If the heating surface of the engine parts is made by silicon nitride ceramics, not only can improve the quality of diesel engine, save fuel, but also can improve the thermal efficiency. silicon nitride powder chemical component: Si3N4NCaOCAlFe≥≤80-9832-390.251.50.30.250.25 Note: 1. This product is suitable for the smelting of stainless steel and special alloy steel together with the making of special refractory materials, it can also be used in national defence, electronic and casting industries. 2.The sizes of silicon nitride can be controlled to be 0-400 mesh by adjusting its components based on the clients' requirements. Except silicon nitride powder,we also produce silicon nitride riser tube,heater or thermocouple protection tube.Here enclose our product photos for your reference: Welcome to inquiry us whenever.We are glad to quote our best price to you asap.
