White Fused Alumina for Refractory

As a kind of refractory materials, white fused alumina is generally used for aggregate and fine powder, because it has the characteristics of high refractoriness, wear resistance, corrosion resistance, etc., and it also has the characteristics of high load temperature and high temperature volume stability when making products. The products of white fused alumina refractories include iron making castables, corundum bricks, magnesia-alumina-carbon bricks, etc.
