PREPARATION OF TITANIUM DIBORIDE AND BORON NITRIDE POWDER

摘要

A process for the simultaneous production of a mixture of titanium diboride powders and boron nitride powers which comprises the steps of: a) mixing together at least one titanium-containing material, at least one boron-containing material, particulate carbon and at least one nitrogen-containing compound in an amount sufficient to produce titanium diboride and boron nitride powders; b) heating the mixture of step (a) to an elevated temperature to produce a synthesized titanium diboride and boron nitride mixture; c) washing the synthesized titanium diboride and boron nitride mixture of step (b) in a solution followed by filtering to remove any excess oxides and then drying the residue; and d) pulverizing the residue of step (c) to produce a powdered mixture of titanium diboride and boron nitride.
