摘要:
A ceramic composition for use in cathode and interconnect materials in solid oxide fuel cells and other electrolytic gas separation systems, such as oxygen separation systems, comprising Lanthanum doped with either Calcium, Strontium, or Barium, in combination with Coboltite, Chromite and Ferrite Oxides.
摘要:
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.
