Abstract: Sodium β/β″-Al2O3 films were prepared by the reaction of spinel-α-Al2O3 compo-site substrate with Li2O and Na2O vapour.The influnences of MgO added to the substrateson the phase composition and electrical conduction property of the films were investigated.The results showed that the addition of MgO to the substrate in weight ≤1% ~2% could en-hance the β″-Al2O3 phase content and there fore improve the ionic conductivity of the film.

Key words: Naβ/β″-Al2O3, film, composite, spinel, ionic conductivity
