Wpływ defektów tlenowych na zmiany temperaturowe przewodnictwa elektrycznego niestechiometrycznego niobianu sodu

Abstract

Measurements of electrical conductivity of nonstoichiometric $NaNbO_3$ were made in the air atmosphere under normal and reduced pressure. It was stated that the value of electrical conductivity is strongly effected by deviation from stoichiometry. The activation energy and phase transitions temperatures were also obtained.
