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.

Abstract: Apparatus usable in the electrolytic treatment of electroactive species in a solution include a porous electrode which is supported across a fluid flow path in such a manner that fluid flowing along the flow path must pass through an effective portion of the electrode.
