Fused Spinel(Magnesia Alumina Spinel)

Magnesia Alumina Spinel is melted by high-purity caustic calcined magnesia and superior alumina through arc furnace. It has the characteristic of high density, the good performance of heat and shock resistance as well as the strong corrosion resistance. It was mainly used to produce high level castables, sliding gate and ladle bricks, ect.

Black Silicon Carbide

Silicon carbide is a man-made material manufactured in electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials. Silicon carbide is an extremely hard material (Mohs hardness 9.25), is chemically inert and does not melt. it is widely used grinding wheels,and also used as refractory material and metallurgical additive.

Green Silicon Carbide

Green silicon carbide is a high-purity hexagonal crystalline silicon carbide produced from high-purity quartz sand and petroleum coke. It is refined through high-temperature smelting in an electric resistance furnace at approximately 2,300°C, followed by crushing, screening and magnetic separation.
