Abstract
A method of making magnetizable abrasive particles includes: moistening the outer surfaces of ceramic particles with waterglass to provide moistened ceramic particles. Magnetizable particles are contacted with the moistened ceramic particles to provide powder-coated ceramic particles. The powder-coated ceramic particles are heated to at least a temperature sufficient to bond the magnetizable particles of the powder-coated ceramic particles to the respective ceramic particles thereby providing the magnetizable abrasive particles. On a respective basis, each magnetizable abrasive particle comprises a respective ceramic particle having a magnetizable particles bonded thereto.
