Abstract
Titanium oxide-containing aluminum oxide particles are based on corundum melted in an electric arc furnace from calcined alumina. The particles may have an aluminum oxide content of less than 97.0% by weight, a titanium oxide content ranging from 1.3% by weight to 1.8% by weight, and a zirconium oxide content of ranging from 0.02% by weight to 0.1% by weight. The aluminum oxide particles may have an arithmetic mean compactness of less than 0.8.
