Magnetizable abrasive particle and method of making the same

A method of making magnetizable abrasive particles, the method comprising steps:

• a) providing ceramic particles, each ceramic particle having a respective outer surface;
• b) moistening the outer surfaces of the ceramic particles with waterglass to provide moistened ceramic particles;
• and
• c) contacting magnetizable particles with the moistened ceramic particles to provide powder-coated ceramic particles;
• and
• d) heating the powder-coated ceramic particles 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, wherein, on a respective basis, each magnetizable abrasive particle comprises a respective ceramic particle having at least some of the magnetizable particles bonded thereto, and
• wherein, on a respective basis, each ceramic particle comprises a receptive surface and at least one other surface, wherein some of the magnetizable particles are bonded preferentially to a contiguous area of the outer surface of the ceramic particles that includes the receptive surface, and wherein a majority by area of the at least one other surface is free of magnetizable particles bonded to the ceramic particle.
