THERMOELECTRIC MATERIALS FOR POWER CONVERSION. Quarterly Progress Report No. 6, May 1, 1960 - July 31, 1960
Materials research on ternary compounds and transition metal silicides together with high temperature thermal diffusivity measurements on AgSbTe/sub 2/, Ge and Si are described. Specimens of stoichiometric AgSbTe/sub 2/ were found to contain about 2% of a separate phase which is probably Ag/sub 2/Te. The materials represented by (Cu, Ag, Au)/sub 2/Te were examined and a single-phase solid Ag/sub 3/CuTe/sub 2/ was prepared. It was found to be an n-type semiconductor. The transition metal silicides were examined further and it was concluded that there is only a very small possibility of obtaining useful materials for high temperature thermoelectric applications from this class of compounds. Measurements of thermal diffusivity on Ce and Si were made at temperatures up to 800 deg C with an experimental accuracy of 2%. An analytical method for the estimation of bismuth in thermoelectric materials is described. (auth)
