AI Article Synopsis
- Metastable ZnO-LiMeO solid solutions were created by reacting ZnO with LiMeO complex oxides at high pressure and temperature.
- These solid solutions can maintain a single-phase rock-salt structure with up to 80 mol% ZnO even when cooled to room temperature.
- The study revealed that these solutions are thermally stable up to 1000 K, with thermal stability and decomposition characteristics varying based on the type of cations used.
Article Abstract
Metastable ZnO-LiMeO (Me = Sc, Ti, Ta) solid solutions with a rock-salt structure were synthesized through the solid-state reaction of ZnO with LiMeO (n = 3, 4, 5) complex oxides at 7.7 GPa and 1300-1500 K. In all investigated systems, single-phase rock-salt solid solutions can be quenched down to ambient conditions in a wide (up to 80 mol% ZnO) concentration range. The phase composition, thermal stability, and thermal expansion of the recovered rock-salt solid solutions were studied by synchrotron powder X-ray diffraction. At ambient pressure, these solid solutions exhibit high thermal stability (up to 1000 K), with the decomposition temperature and decomposition products depending on the nature of the multiple charge cations.
