Low-sodium white fused alumina 0.1% Na2O

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 ℃ followed by a slow solidification process. Strict control over the 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-sized fractions to suit the end-use
