Brown fused Alumina (also know as brown corundum or brown aluminium oxide) is produced by fusion of calcined bauxite in Electric arc furnaces at high temperature of about 2000 degree celsius. The end product has low iron content making it particularly valuable in refractory applications. BFA has a high refactoriness, is extremely hard and stable. It is of compression strength, high toughness, good self-sharping, lower expansion coefficient, no rusty spot, good hydrophily, high cleanliness, heat resistance and chemical stability. |
Application: - shaped and unshaped refractory products - abrasive products - blasting medias - brake and friction linings |
