摘要： 采用水热法合成了系列磷酸盐化合物Na1+xAlxZr2-xP3O12,该系列化合物具有NASICON型三维骨架结构。考查了反应物料配比、晶化时间、晶化温度等实验条件对产物物相及掺入Al含量对化合物的结构与性能的影响。实验结果表明:在0≤x≤0.33的范围内,可水热合成出Na1+xAlxZr2-xP3O12纯相,而且具有良好的热稳定性。该系列化合物的离子电导率测试结果表明,其电导率与掺入的Al含量有关。

Abstract: Aseries compounds of Na1+x AlxZr2-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.Apure 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 ACimpedance 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 NASICONstructure can be directly obtained by hydrothermal syntheses.
