Abstract
A process for synthesizing titanium carbide, titanium nitride or titanium carbonitride. The process comprises placing particles of titanium, a titanium salt or titanium dioxide within a vessel and providing a carbon-containing atmosphere within the vessel. The vessel is heated to a pyrolysis temperature sufficient to pyrolyze the carbon to thereby coat the particles with a carbon coating. Thereafter, the carbon-coated particles are heated in an inert atmosphere to produce titanium carbide, or in a nitrogen atmosphere to produce titanium nitride or titanium carbonitride, with the heating being of a temperature and time sufficient to produce a substantially complete solid solution.
Claims5
A process for synthesizing titanium carbide, titanium nitride or titanium carbonitride powder, the process comprising:
- a) placing particles of titanium, a titanium salt or titanium dioxide within a vessel and providing a carbon-containing gaseous atmosphere within the vessel, said particles appropriately sized to yield a powder having average particle sizes in the range from 0.05 .mu.m to 0.2 .mu.m;
- b) heating the vessel to a pyrolysis temperature sufficient to pyrolyze the carbon to thereby coat the particles with a carbon coating;
- and
- c) thereafter heating the carbon-coated particles in an inert atmosphere to produce titanium carbide or in a nitrogen atmosphere to produce titanium nitride or titanium carbonitride, said heating being of a temperature and time sufficient to produce a substantially complete solid solution.
