White fused alumina is from the reduced fusion of high purity alumina powder containing aluminium oxide(Al2O3). White fused alumina has a very high refractory temperature and acid resistance. Alkali corrosion resistance is stable in chemical content and has high true gravity/density, low porosity rate, and thermal shock resistance. It’s an excellent corundum aluminium oxide refractory material. White fused alumina is an essential high-end material for producing shaped and unshaped refractory products.
