Wyznaczanie współczynnika efektywności termoelektrycznej niobianu sodu

Abstract

To evaluate the possibilities of using sodium niobate in thermo-electric converters transforming heat energy into electric energy, the temperature changes of electric conductivity, of Seebeck coefficient and of the thermal conductivity of sodium niobate $NaNbO_3$ in clear state and with the admixture of $La_2O_3$ have been examined. The obtained results have been used to calculate the coefficient of thermo-electric efficiency of the examined materials.
