Abstract
Bonded abrasive articles are described wherein a metal boride modified, lead-free vitreous matrix binds abrasive grains, such abrasive articles demonstrate improved performance over vitreous bonded abrasive articles with known vitreous matrices. Vitreous bond precursor materials are described including admixtures comprising lead-free vitreous precursor material and powder of metal boride(s), and admixtures comprising metal boride modified, lead-free vitreous particles. Methods are described for producing vitreous bonded abrasive articles having abrasive grains bound by metal boride modified, lead-free vitreous matrices.
