Abstract
An abrasive material giving improved results when employed as the abrasive grit in grinding wheels employed for heavy duty snagging of carbon steels and stainless steels is produced by the rapid quenching of a fusion of a mixture of alumina, zirconia, and magnesia, the zirconia content being 22 to 28%, by weight, and the weight ratio of magnesia to alumina being between 0.014 and 0.029. The solidified product is impact crushed to produce coarse abrasive grits in the grit size range appropriate for heavy duty snagging.
