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.
Claims15
An abrasive article comprising:
- an abrasive body having abrasive grains contained within a bond material, wherein the abrasive grains comprise microcrystalline alumina, and wherein the bond material comprises less than about 1.0 mol % phosphorous oxide (P2O5), and a ratio between a total content of sodium oxide (Na2O) measured in mol % and a total content of potassium oxide (K2O) measured in mol % defined by [K2O/Na2O] having a value greater than about 1;
- wherein the bond material comprises a total content of alkali oxide compounds of less than 12 mol %;
- and
- wherein the bond material comprises silica and wherein a ratio between a total content of silica (SiO2) measured in mol % and a total content of alkali oxide compounds (Caoc) measured in mol % expressed as [Caoc/SiO2] is greater than about 0.18.
An abrasive article comprising:
- an abrasive body including abrasive grains contained within a bond material, wherein the abrasive grains comprise microcrystalline alumina, and wherein the bond material comprises less than about 2.0 mol % lithium oxide (Li2O), and less than about 9 mol % boron oxide (B2O3), and wherein the bond material comprises between about 4.0 mol % and about 10 mol % potassium oxide.
