Fused Magnesia-Alumina Spinel

Product Details

Fused alumina magnesia spinel has the characteristics of large volume density, low water absorption, high temperature resistance, small thermal expansion coefficient, good thermal stability, good appearance and color, slag resistance, corrosion resistance and so on.

Fused magnesia alumina spinel is widely used in refractory materials, steel making, cement rotary kiln and glass industry furnaces. It is an ideal raw material for the production of high performance castables, sliding nozzles, ladle lining bricks and other refractory materials and investment castings.
