“…Li3 ,4(Si0 ,4Xo &)4.8.9. 12 Shannon et aL3 believed their highly conducting composition, x=0.30, to be a vacancy solid solution based on Li4Si04, whereas our results, in agreement with Fitch et a1., 16 indicate the structure to be rather an Li' interstitial solid solution based on the y-Li3P04 structure. This misassignment is readily understandable since there is considerable similarity between the X-ray powder patterns of Li4Si04 and the y phase.…”

In the system Li4Si04-Li,S04, phase-diagram studies show the existence of a narrow range of stable y solid solutions, Li4-2pw(Si, -xS,)04: 0.30 < x < 0.045. These have high Li+ ion conductivity with maximum values for x z 0 . 4 0 of 1.32 x S cm-' at 300 "C and an activation energy of 0.80 eV.The y solid solutions are structurally related to orthorhombic y-Li,PO, and contain interstitial Li' ions; for x = 0.40, a=6.187(2) A, b=10.621(3) A, c=5.008(3) A.

“…The mean bonds lengths /Li-OS and /Zn-OS are, 1.968 and 1.958 ( A, respectively, calculated using the data for e-, a-, CR1-and d I -LiZnPO 4 (7,(9)(10)(11)14) (the mean bond length /P-OS is 1.539 ( A for these compounds). Li/Zn disorder has been described in both silicates and germanates, e.g., (37)(38)(39)(40). Slight disorder was also proposed for d ILiZnPO 4 prepared by hydrothermal synthesis and investigated using synchrotron X-ray powder diffraction (10).…”
