Zjawiska termoelektryczne w układzie $Pt-NaNbO_3-Pt$

Abstract

Temperature changes of the electrical conductivity and of the Seebeck coefficient for the ceramics $NaNbO_3$, and $NaNbO_3$ + 0.2% mol $La_2O_3$, have been investigated. The obtained results have been used to define the type of conductivity and to determine the activation energy of the charge carriers.
