Claims19
A method of forming an abrasive article comprising:
- providing a green body comprising abrasive particles including microcrystalline alumina;
- and
- heating the green body via microwave radiation to form a bonded abrasive body including the abrasive particles and a bond material comprising a vitreous phase, wherein after heating the bonded abrasive body comprises a density variation of not greater than 11%, wherein the density variation is defined by the equation [(Dt−Da)/Dt]×100%, wherein Dt represents a target density of the bonded abrasive body and Da represents an acual density of the bonded abrasive body.
An abrasive article comprising:
- a bonded abrasive body formed by microwave radiation including:
- a bond material comprising a vitreous phase;
- abrasive particles comprising microcrystalline alumina contained within the bond material;
- and
- wherein the bonded abrasive body comprises a density variation of not greater than about 11%, wherein the density variation is defined by the equation [(Dt−Da)/Dt]×100%, wherein Dt represents a target density of the bonded abrasive body and Da represents an actual density of the bonded abrasive body.
