  • Publication number: 20100284895
    Abstract: It is an object of the present invention to provide a method for manufacturing tantalum carbide which can form tantalum carbide having a prescribed shape using a simple method, can form the tantalum carbide having a uniform thickness even when the tantalum carbide is coated on the surface of an article and is not peeled off by a thermal history, tantalum carbide obtained by the manufacturing method, wiring of tantalum carbide, and electrodes of tantalum carbide. The tantalum carbide is formed on the surface of tantalum or a tantalum alloy by placing the tantalum or tantalum alloy in a vacuum heat treatment furnace, heat-treating the tantalum or tantalum alloy under a condition where a native oxide layer of Ta2O5 formed on the surface of tantalum or tantalum alloy is sublimated to remove the Ta2O5, introducing a carbon source into the vacuum heat treatment furnace, and then heat-treating.
