近年来，能够多离子传输的多相材料已经成为各种电化学器件的有吸引力的候选者。在这里，我们提供的实验结果制造的复合电解质由一维快速钠离子导体，锆镓酸钠，和氧离子导体，氧化钇稳定的氧化锆。该复合材料是通过气相转化机制合成的，并详细讨论了这一过程的动力学。使用衍射，电子显微镜和电化学阻抗谱技术的样品进行了表征。具有较细晶粒结构的样品由于每单位面积较大的三相边界（TPB）而表现出较高的动力学速率。总电导率拟合为Arcidius型方程，活化能范围为
In recent years, multi-phase materials capable of multi-ion transport have emerged as attractive candidates for a variety of electrochemical devices. Here, we provide experimental results for fabricating a composite electrolyte made up of a one-dimensional fast sodium-ion conductor, sodium zirconogallate, and an oxygen-ion conductor, yttria-stabilized zirconia. The composite is synthesized through a vapor phase conversion mechanism, and the kinetics of this process are discussed in detail. The samples are characterized using diffraction, electron microscopy, and electrochemical impedance spectroscopy techniques. Samples with a finer grain structure exhibit higher kinetic rates due to larger three-phase boundaries (TPBs) per unit area. The total conductivity is fitted to an Arrhenius type equation with activation energies ranging from
