WA – White Fused Alumina WA is a fused white alumina abrasive powder produced by crushing fused alumina and sorting the particles into a uniform size. The resulting compound has the following characteristics: An α‑type corundum crystal configuration At least a 96.0% pure aluminum oxide (Al2O3) composition A hardness nearly equal to silicon carbide A closely

—Description The WFA is the main raw material for the production of unshaped and shaped refractory materials. Commonly used in ladle castables, iron runner materials, refractory gunning mix materials and other monolithic refractory products; For the shaped refractory materials, it is mainly used in the high-quality raw materials of corundum brick, corundum mullite, refining steel

White aluminum oxide was made from the high quality alumina by melting above 2200℃ in the electric arc furnace and cooling.   White aluminum oxide is white with the main crystal phase alpha-Al2O3.   White aluminum oxide produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability

White Fused Alumina This synthetic product is fused in an arc furnace with high-quality aluminium oxide as raw material. Al2O3content equals as much as 99% and Na20, K20, CaO, SiO2, Fe2O3 are the admixtures. In comparison with Brown Aluminium Oxide it has higher hardness (over 9 in Mohs scale) and microhardness (2100kG/mm2). It is also more

White fused alumina is made in arc furnace with high grade processed alumina as raw materials. It has higher hardness , high toughness, and also characterized by its high purity. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel. also widely used for bonded and coated abrasives, polishing, precision casting and so on.
