This invention relates to abrasive particles and process for their preparation. The particles consist essentially of a matrix of titanium carbide, zirconium carbide and tantalum carbide, at least partially in solid solution form and grains of crystalline titanium diboride dispersed throughout the carbide matrix. These abrasive particles are particularly useful as components of grinding wheels for abrading steel.
