| 摘 要： | 本文用差热分析和X射线衍射的方法对Li4GeO4-Zn2GeO4赝二元系相图进行了研究。结果指出,文献中所报道的锂离子导体Li14Zn(GeO4)4不是化合物,而是含Zn2GeO4的以Li4GeO4为基的固溶体,由于Zn2GeO4的加入,使Li4GeO4的高温相稳定存在于室温。根据研究结果,提出了关于Li14Zn(GeO4)4多晶陶瓮样品在室温长期放置后,电导率明显降低的解释。

| Abstract: | The pseudo-binary system Li4GeO4-Zn2GeO4 has been studied by means of DTA and X-ray diffraction techniques. According to the phase diagram established, Li14Zn(GeO4)4 ("LISICON") is a solid solution based on the high temperature phase of Li4GeO4 which is stabilized to room temperature by the addition of Zn2GeO4. Long period "aging" at room temperature of the ceramic specimens of "Lisicon" reduced its conductivity remarkably, for which the authors propose an additional explanation. |
