Abstract:

Applied research and development is reported on a laboratory thermoelectric generator operating at a hot junction temperature of 1200 C and a cold junction of 500-700 C in a vacuum of 1100,000 mm Hg. Apparatus needed to fabricate and test candidate junction materials and modules for use with a new proprietary thermoelectric material, MCC 50, are described. Tests to be conducted include mechanical strength, sublimation loss, electrical properties, thermal shock and resistance to solid-state diffusion. Preliminary efforts to produce modules of MCC 50 in combination with tantalum, titanium, molybdenum and tungsten by hot press, resistance welding and brazing were only partially successful. However, a graphite-MCC 50-graphite module was produced which exhibited juntions of promising mechanical strength and preliminary measurements of its electrical properties were made. Author
