White aluminium oxide/white fused alumina(WA)
Introduction
Al2O3 99.53%........... NaO 0.3%......... Fe2O3 0.1%......... Magnetic material content 0.0023%..... Color white … … hardness(mohs) 9… …. Ture density 3.9
Marterials: alumina
White aluminium oxide is electrically fused in the furnace with high grade bayer processed alumina as raw material.. It has high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability .
