Fused Spinel
(Alumina-Magnesia Spinel)

Fused Spinel, Alumina-Magnesia Spinel is one of the most resistant refractory compounds. It has great features such as 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. Use 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, great color, strong resistance to corrosion and anti-detonation. It adopts high pure MgO and Chemical Al2O3 to smelt by EAF. Applications include but are not limited to the proof of EAF, basic oxygen furnace, steel ladle, intermediate zone cement rotary kiln, etc.
