Description:
White Fused Alumina Powder is a high purity α-type alumina powder containing no less than 99.6% Al2O3. This product is developed to maintain a low Na2O amount, as low as 0.09% or less, so it has an excellent insulation capability. White Fused Alumina Powder can be used as insulation coating material for heater of electronics tubes and various insulating film materials. We have produced this range by fusing calcined alumina at high temperature in an electrical furnace, alumina lump procured is then graded and crushed to produce WFA fines and grains for refractories and abrasives. White Fused White Fused Alumina Powder is used in many applications including grinding and cut off wheels, refractories and ceramic shapes, coated abrasives, investment casting shells, laminates, coatings, blasting abrasives, lapping and polishing, and many, many more.
