【Abstract】 A series compounds of Na_1+x Al_xZr_2-x（PO4）₃ which have three-dimensional net work structure of NASICON have been prepared by using hydrothermal techniques. The synthesis conditions of these compounds, the crystallizing time, temperature and the amount of the reactants, which could effect on the products, have been detected.A pure crystal phase could be obtained when 0≤x≤0.33 by using hydrothermal techniques. The relation ship of the structures and properties with the amount of Al of the compounds has been studied. The compounds prepared by this method have very good thermal stabilities. The cells of the compounds decrease when the amount of Al in the compounds increases.Ionic conductivity and conducting activation energy of samples have been determined by means of AC impedance technique. The conductivity of the compounds increases with the increasing of the amount of Al in the compounds when 0≤x≤0. 33. These results show that the compounds with NASICON structure can be directly obtained by hydrothermal syntheses.更多还原
