Notes:
Na2O·x Al2O3 (x= 9, 11)films have been obtained by sol–gel method. Crystallization processes during heat treatments have been investigated by X–ray diffraction analysis. A metastable phase with the mullite structure, λ–Na2O·xAl2O3, has been observed starting from 800°C. Films remained stable after a heat treatment at 1000°C for 250 h. Impedance spectroscopy measurements showed that the films of λ-Na2O·x Al2O3 possess a large three–dimensional ionic conductivity at 400°C.
