ABRASIVE GRAIN CONTAINING ALUMINA AND ZIRCONIA

摘要

2142898 9407809 PCTABScor01 A method of preparing preferred abrasive grain includes: preparing a dispersion including alpha alumina oxide monohydrate and zirconia sol therein; converting the dispersion to base grit material; and sintering the base grit to form abrasive grains. The presence of the zirconia sol within the dispersion from which the base grits are formed provides an improved abrasive grain. The improved abrasive grains are useful in abrasive products.
