THERMOELECTRIC MATERIALS

Abstract

Standard ceramic bodies were prepared of all standard series of additions to TiO2. A programer was constructed to produce a controlled linear heating rate in the furnace of the Skinner Thermal Conductivity Comparator. Equipment and circuitry for electrical measurements were improved. The measuring system was doubled in capacity. Standard reference curves of delta T vs T were established. The Seebeck coefficient was determined as a function of temperature on the following standard series: (1) cubic ZrO2-7 m/o Y2O3 solid solution plus La2O3 additions; (2) cubuc ZrO2-15 m/o CaO solid solution plus Nb2O5 additions; and (3) cubic ZrO2-15 m/o CaO solid solution plus La2O3 additions. Nb2O5 was more effective than La2O3 in increasing the Seebeck effect in cubic ZrO2 solid solutions.
