ABSTRACT:
Abrasive granules are produced from alumina or an alumina-zirconia mixture by melting the oxide material and rapidly cooling the melt. To control the solidification velocity, the melt is cast into a molten chloride of Na, Ca, Ba, Mg or mixtures thereof to cool the oxide material melt, the chloride is separated from the cooled and solidified oxide material, and thereafter abrasive granules are produced from the solidified oxide material.
