PHASE DIAGRAM OF THE PSEUDO-BINARY SYSTEM Li4GeO4-Zn2GeO4
Li4GeO4-Zn2GeO4赝二元系相图的研究

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.
