Abstract
Official abstract text for this publication.
The invention relates to molten grains having the following chemical composition in wt % in terms of oxides: Al 2 O 3 : balance to 100%; ZrO 2 +HfO 2 : 16-24%; MgO in an amount such that the weight ratio (ZrO 2 +HfO 2 )/MgO is between 25 and 65; other species: 0-2%. The grains can be used as abrasive grains.
First claim
Opening claim text (preview).
The invention claimed: 1. Fused grains having the following chemical analysis, as percentages by weight on the basis of the oxides: Al 2 O 3 : balance to 100%; ZrO 2 +HfO 2 : 16-24%; MgO in an amount ranging from greater than 0.35% to less than 0.80%; wherein a (ZrO 2 +HfO 2 )/MgO weight ratio is 25 or more to less than 49; a proportion of zirconia stabilized in tetragonal form represents at least 30% to less than 66% of the total amount of zirconia; and other species:…
