Сomplex doping niobium oxide with ionic conductivity.
Abstract
The novel compounds Li6MNb4O14 (M = Zn, Mg) have been synthesized and characterized in the Li2O-MO-Nb2O5 (M = Zn, Mg) system. The synthesized phases were investigated by XRD, DTA and the chemical analysis. Specific conductivity and energy of activation of each compounds and the sample that doping by titanium oxide has been found. Comparison of absorption IR-spectra of investigated compounds and of samples Li6ZnNb4O14 having isotope on lithium and zinc has been compared.
