摘要：
The structural phase transitions of LiTi2(PO4)3, LiInNb(PO4)3, and LiZr2(PO4)3 have been studied by X-ray diffraction, impedance spectroscopy, 7Li NMR spectroscopy, and calorimetry. The results indicate that, as the temperature is raised, the lithium ions in the structure of LiTi2(PO4)3 and LiInNb(PO4)3 redistribute between the M1 and M2 sites. The thermal expansion coefficients along the crystallographic axes of LiTi2(PO4)3 and LiInNb(PO4)3 are estimated.
