'Mixture of fused alumina-zirconia grains and grinding processes of fused alumina-zirconia grains.'

摘要

A molten alumina/zirconia grain mixture having the following chemical composition, in wt %: ZrO2+HfO2: 35 to 45.5%; Al2O3: 43.7 to 65%; other oxides: 10%; SiO2: 0.8%, which simultaneously adheres to a granulometric condition and to a densimetric condition.
