Refractory Materials


Fused Magnesia-Alumina Spinel (fused magnesium-aluminate spinel) is made of high purity raw materials in electric arc furnaces. The maximum amount of spinel crystals is achieved by using pure raw materials and electric arc-furnaces. The product has a high thermal shock resistance, slag corrosion resistance, and good refractoriness.
