Fused Spinel
(Alumina-Magnesia Spinel)

Fused Spinel, Alumina-Magnesia Spinel is one of the most resistant refractory compounds. It has great features like a low thermal working temperature, outstanding refractoriness, thermal stability and chemical stability.

Refractory Raw Material - Fused Spinel

Fused Spinel, Alumina-Magnesia Spinel is a highly recommended refractory raw material. Using our high-quality pre-reacted ALUMINA-MAGNESIA SPINEL for developing high purity refractories in both monolithic and brick form.

Our high quality Fused Spinel has high bulk density and great color. It has strong resistance to corroding and anti-detonation. It adopts high pure MgO and Chemical Al2O3 to smelt by EAF. Application include but not limited to the proof of EAF, basic oxygen furnace, steel ladle, intermediate zone cement rotary kiln, etc.
