OXIDE THERMOELECTRIC MATERIALS

Abstract

Progress is reported on the work performed on the Seebeck coefficient and dc resistivity measurements for (TiO2)x(ZnO)100-x,(ZnFe2O4)100-x (TiO2)x, and (Li2O)x(ZnO)100-x compounds. The resistivity vs temperature behavior of the (TiO2)x(ZnO)100-x series of compounds is similar to that of the (Al2O3)x(ZnO)100-x series. A minimum of resistivity is evident at an intermediate temperature (about 1000 C). When Li2O is added to ZnO the number of conducting electrons in the material is reduced and the electrical conductivity is also reduced. With a nonstoichiometric, cation-deficient compound such as nickel oxide the roles of the additives are reversed. The members of the (ZnFe2O4)100-x (TiO2)x series are not suitable for use as current generators because of their relatively high resistances. (Author)
