Abstract
An abrasive article having an abrasive body including abrasive grains contained within a bond material, wherein the abrasive grains comprise microcrystalline alumina, and wherein the bond material includes less than about 1.0 mol % phosphorous oxide (P2O5), and a ratio measured in mol % between a total content of sodium oxide (Na2O) and a total content of potassium oxide (K2O) defined by [K2O/Na2O] having a value greater than about 0.5.
Claims19
A method of forming an abrasive article comprising:
- mixing abrasive grains comprising microcrystalline alumina with a bond material powder, wherein the bond material powder comprises not greater than about 15 wt % alkali oxide compounds;
- forming the mixture into a green article;
- and
- heating the green article to a firing temperature of at least about 1150° C. to form an abrasive article having abrasive grains contained within a vitreous bond material.
