Abstract
Official abstract text for this publication.
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 (P 2 O 5 ), and a ratio measured in mol % between a total content of sodium oxide (Na 2 O) and a total content of potassium oxide (K 2 O) defined by [K 2 O/Na 2 O] having a value greater than about 0.5.
First claim
Opening claim text (preview).
What is claimed is: 1. 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.…
