Fused Spinel (Alumina Magnesia Spinel)

Fused Spinel is a high-purity refractory raw material produced by fusing alumina and magnesia at ultra-high temperatures. It features a dense crystal structure, excellent thermal shock resistance, and outstanding corrosion resistance.

ZE XI MINERAL CO., LTD supplies various grades of fused spinel including AM-65, AM-70, AM-85 and AM-90, widely used in steel, cement, foundry and petrochemical industries.
