WHITE SINTERED ALUMINA

WHITE SINTERED ALUMNA is a fully shrunk, high density, low porosity grains made by sintering process using Reactive Alumina as raw material. The result is a product with unique resistance to all hazard of high temperature service. Crushed, ground and graded Sintered Alumina is the principal ingredient for all high performance alumina refractories above 85% and up to  99%. These include fired shapes, low cement castables, cement free castables, etc. This product is the outcome of landmark research made by Passary Minerals Ltd. as it replaces costly tabular Alumina. Sintered Alumina grains are made under closely controlled manufacturing process and the refractories strength and volume stability are similar to Tabular Alumina at high temperature also. It replaces fused alumina due to its superior spalling resistance properties. Grading can be made as per customer's requirement. Micro fine sintered Alumina is produced in high alumina lined ball mill with superfine classifier.
