ight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, acid and alkali resistance, good thermal stability. It¡¡¥s the high grade refractory materials.
Applications
Dedicated lines produce products for different applications. White fused alumina is highly friable and hence used in vitrified bonded abrasives products where cool, fast cutting action is essential and also in the manufacture of high purity alumina refractories. Other applications include use in coated abrasives, surface treatment, ceramic tiles, anti-skid paints, fluidized bed furnaces and skin / dental care.
