Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ФОСФАТЫ -- ТИТАНАТ ЛИТИЯ Аннотация: Li1 +xTi2 –xGax(PO4)3(x= 0–0.2) NASICON double phosphates are prepared and studied by hightemperature X-ray diffraction, 7Li NMR spectroscopy, impedance spectroscopy, and calorimetry. Doping with Ga3+cations increases cation mobility in LiTi2(PO4)3. Ion conductivity, NMR spectroscopy, and calorimetry data imply the occurrence of a phase transition in LiTi2(PO4)3 and in products of partial gallium-for-titanium substitution Полный текст |
