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.
