White Fused Alumina is an important raw material for advanced refractories and abrasives, it's made from industrial aluminum powder, which is melted in EAF with a high temperature over 2000 degrees then cooled, crushed and shaped, iron is removed by magnetic separation, finally sieved into a variety of particle sizes. Widely used as raw material in refractories,ceramics shapes,grinding wheels,sandpaper,blasting media,metal preparation,laminates,coating,lapping,polishing,grinding,and hundreds of other applications.
