| Popis: | Various crystalline Li-M-Silicate (M=Mg, Al, Ti) composite compounds were prepared and their cation transport properties examined. The extent of reaction was tested under the fixed M:Si molar ratio of 1 by changing the Li molar ratios from 0.1, 0.3, 0.5, 0.7 to 1. The physiochemical properties of the materials obtained were analyzed by using ICP-AES, XRD, TG/DTA and SEM and conductivity measurements were carried out with an LCR meter. According to the results found in the substituted polyvalent Mn+ ion and the added lithium contents, each polycrystalline sample showed various crystal structures and conductivity. The highest conductivity was obtained from Li-Al-Silicate compound (Li: Al: Si=0.3∶1∶1), which contains the\(Al_6 Si_2 O_{13^ - } \) LiAlSiO4 transient phase to facilitate free space for the lithium ions mobility in the crystal lattice. |
