THERMOELECTRIC MATERIALS
Abstract
Three hundred twenty-three oxide, silicate, and metal hydride combinations were prepared and fabricated into test specimens by a variety of forming and firing techniques. Of these combinations, 309 were examined electrically for Seebeck effect and resistivity from 600 to 1200 C; the remaining few failed in test. None of the compo sitions tested gave indication of truly efficient conversion of heat to electricity; the TiO2 plus 2.0 mole percent Nb2O5 had an approximate figure of merit of 7.0 x 10 to the -5th power per degree centigrade.
