Introduction
Dense Fused Alumina(DFA) is obtained from the fusion of high purity industrial alumina in electric arc furnaces with special technological process of production.
Dense Fused Alumina(DFA) has the characteristics of high melting point, high bulk density and low porosity. It is recognized as the most outstanding refractory in the corundum series. Dense fused alumina is widely used in iron and steel, cement, ceramics and petrochemical, etc.
