Product introduction of silicon carbide castable
Silicon carbide castable charge was produced from advanced silicon carbide and industrial silicon powder. This is an amorphous refractory. It is obtained with refractory substances, refractory powder, binders and other additives. It is a new type of refractory that does not require calcination.
Features of silicon carbide castable
silicon carbide castable: good wear and corrosion resistance, high temperature resistance, high thermal conductivity, weak swelling and good thermal shock resistance.
Details of silicon carbide castable
Silicon carbide castable, with its high hardness, electrical conductivity, high temperature resistance and resistance, is widely used for abrasives, hardeners, ceramics and refractories. Silicon carbide castable has a molar hardness of 9.5 and a grinding power of 0.25 to 0.28, higher than that of corundum (about 0.01).
