Product Description

Raw Material and Process of Production

  • White Fused Alumina is a high purity, synthetic mineral.
  • It is manufactured by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000oC followed by a slow solidification process.
  • Strict control over quality of raw materials and fusion parameters ensure products of high purity and high whiteness.
  • The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use.

Application :

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.
