Abstract
Metastable LiMeO2–ZnO (Me=Fe 3+, Ti3+) solid solutions with a rock salt crystal structure have been synthesized by the solid-state reaction of ZnO with LiMeO2 complex oxides at 7.7 GPa and 1350–1450 K. The structure, phase composition, thermal stability and thermal expansion of the recovered samples have been studied by X-ray diffraction with synchrotron radiation. At ambient pressure, rock salt LiMeO2–ZnO solid solutions are kinetically stable up to 670–800 K, depending on the composition.Keywords
