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
2000˚C 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.
