PROBLEM TO BE SOLVED : To provide a thermoelectric conversion material which can be used under a hot and inferior environment because immediate establishment of a power generation system utilizing exhaust heat under a hot and inferior environment is needed although it is difficult for conventional thermoelectric conversion material to design and assure an excellent material operating stably without slowing down the performance at high temperature (700 K or above). SOLUTION : A carbon doped rare earth multi-boride represented by general formula REB62+XCY(X and Y are arbitrary numerical values shown by -12COPYRIGHT : (C)2007, JPO&INPIT
