PROBLEM TO BE SOLVED: To produce a carbon composite material for a reducing atmosphere furnace exhibiting an excellent reductive gas reaction suppressing effect even in a high temp. reductive gas atmosphere more than 1000 deg.C and capable of largely prolonging a product life. SOLUTION: In the carbon composite material 1 for the reducing atmosphere furnace, a TaC coating film 3 having a crystal structure with particulates aggregated is formed on a surface of a carbon base material 2, and a composition rate (Ta/C) of the coating film is 0.8-1.2. And in the production method of the carbon composite material 1 for the reducing atmosphere furnace, the TaC coating film 3 is formed on the surface of a graphite base material 2 so that its composition rate (Ta/C) may be 0.8-1.2 by using metallic Ta as a target and a reactive gas by an arc ion plating(AIP) type reactive deposition method. |
