Abstractβ-β″-Al2O3precursor powder was successfully prepared by a solid-phase sintering method with Li2CO3, Na2CO3 (as the sources of Li20 and Na20, respectively) and β″-Al2O3 powder as the raw materials. The precursor was characterized by X-ray diffraction (XRD) and scan- ning electron microscope (SEM). The results indicate that the amount of Na20 in the raw materials has a great effect on the formation of β″-Al2O3 in the β-β″-Al2O3 precursor. When Na20 content is 10 wt%, the content of β″-Al2O3 phase reaches the maximum value of 86.24 wt% in the precursor. The β-β″-Al2O3 ceramic was prepared from β-β″-Al2O3 precursor powder by isostatic pressing and burying sintering process. The conductive property of the β-β″-Al2O3 ceramic was examined by electrochemical impedance spectroscopy (EIS) method, and the density was measured by the Archimedes method. The results reveal that when 10 wt% Na20 was added, the sample exhibits the best performance with the lowest resistivity of and the highest density of 3.25 3. A solid electrolyte battery of PtlSnQ, Na2SnO3113 β-β″-Al2O3 Na CrO2, Cr2lO3 Pt was assembled by the β-β″-Al2O3 electrolyte tube to measure the open potential of the resulting battery, and the formation free energy of sodium stannate was calculated In the temperature range of 1273-773 K, the relationship between formation free energy of sodiumstannate and temperature was generated as follows:△GNa2SnO3 0=-1040.83+0.2221T±7.54.
