White Fused Alumina is made from reduced fusion of high purity alumina powder and other fillings in electric arc furnace under 2000 degree above
Refractory
Because of its high refractory temperature, acid and alkali corrosion resistant, stable in chemical content, high true gravity/density, low porosity rate, thermal shock resistant,White Fused Alumina refractory grades is an important high end material for production of shaped and unshaped refractory products.Along with Brown Fused Alumina,White Fused Alumina is one of the important refractory material in synthetic corundum family, while with higher Aluminium Oxide content.
Abrasive Tools and Sandblasting
We select quality high purity alumina powder and fuse in electric arc furnace by skilled technicians, and execute standard crush, shape improve, sieving, magnetic content removal and grade into standard FEPA grits for abrasives and sand blasting.
