HIGH TEMPERATURE SEMICONDUCTING COMPOUNDS FOR THERMOELECTRIC POWER GENERATION

Abstract

Certain sulfides, selenides, and tellurides of uranium and thorium were investigated with respect to their potential usefulness as high-temperature thermoelectric materials. Intermediate phases with compositions of the forms MX, MX2,AND M2X3 (where M = Th or U, and X = S, Se, or Te) were synthesized, and their Seebeck coefficients and electrical resistivities measured as functions of temperature. The only material found to have a Seebeck coefficient sufficiently high to be of particular interest was ThS2, with a value of 700 microV/degrees C at 400 C. Determination of the chemical and crystalline composition of the synthesized materials was a difficult problem, and it was recommended that any continuation of the work be concentrated on overcoming this difficulty.
