High Chromium Aluminum Oxide Grit Vitrified Bonded Refactory Supply
Pink Fused alumina Oxide
Product Description
Pink Fused Alumina is produced by doping Chromia into Alumina, which gives the material pink color. The incorporation of the Cr2O3 into the Al2O3 crystal lattice produces a slight increase in toughness and a reduced friability compared with White Fused Alumina.
