Refractory white fused alumina/white fused alumina oxide powder
Product description
Refractory white fused alumina/white fused alumina oxide powder
It is manufactured by the fusion of controlled quality pure grade Alumina in an electric arc furnace at temperatures greater than 2000C 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.
