Abstract
A composition for hard, sintered, tough and wear resistant ceramic articles is described. The composition is comprised of alumina, titanium carbonitride and filaments of titanium diboride or titanium nitride. The ceramic articles made of this composition are isostatically hot pressed or sintered at high temperature in inert gas. The density of the ceramic articles is usually in excess of 99% theoretical density and the hardness is greater than 20 GPa. The process was applied to manufacture ceramic cutting inserts of the above composition.
