Method of manufacturing tantalum carbide material

1. A method of manufacturing a tantalum carbide material in which a tantalum material interposed between a pair of graphite guide members is heated under a carbon source-containing gas atmosphere at 1,500° C. or higher for 0.5 hours or longer to make tantalum carbide from all the tantalum material.

2. The method of manufacturing a tantalum carbide material according to claim 1 , comprising

a process of preparing the tantalum material interposed between the pair of graphite guide members;

a process of placing the tantalum material interposed between the pair of graphite guide members and a hydrocarbon gas source in a container; and

a process of, while the inside of the container is made a closed space, heating the hydrocarbon gas source to generate the carbon source-containing gas and heating the tantalum material under an atmosphere of the carbon source-containing gas to obtain a tantalum carbide material.

3. The method of manufacturing a tantalum carbide material according to claim 2 ,

wherein the hydrocarbon gas source includes hydrocarbons, and

wherein the hydrocarbons include one or both of aromatic hydrocarbons and aliphatic hydrocarbons.

4. The method of manufacturing a tantalum carbide material according to claim 1 ,

wherein the thickness of the tantalum material is 0.1 mm or more and 3.0 mm or less.

5. The method of manufacturing a tantalum carbide material according to claim 1 ,

wherein the pair of graphite guide members are a pair of graphite plates.

6. The method of manufacturing a tantalum carbide material according to claim 1 ,

wherein the carbon source-containing gas is generated by heating a hydrocarbon gas source which includes hydrocarbons and graphite powder.
