RESEARCH PROGRAM ON SEMICONDUCTING COMPOUNDS FOR THERMOELECTRIC POWER GENERATION AT HIGH TEMPERATURES
Abstract
An investigation is being made of semiconducting combinations of the heavy refractory metals with high-atomic weight elements of groups 4B, 5B, and 6B of the periodic table, and of less metallic variations of the refractory superlattice intermetallic compounds as possible materials for high-temperature thermoelectric elements. The following compounds were studied: (1) arsenic compounds, (2) Hf-Bi, (3) Re-Te, (4) Hf-Se, (5) Re-Ge, (6) Hf-Sb, (7) Hf-Ge, (8) Hf-Te, and (9) W-Se-Te. Methods are being developed for gravimetric chemical analysis of the materials being prepared. Spectrographic analysis was made of most of the samples to indicate the level of impurities incidently added to the materials during processing. The apparatus for measurement of thermoelectric properties was rebuilt with an increase of nearly 200 degrees C in the maximum temperature which can be measured.
