Rietveld analysis was performed to confirm the different phases associated in the formation of LiFeO2. Quantitative Rietveld refinement revealed that sample contains: 39.9 wt% of cubic α – LiFeO2 phase, 58.5 wt% of monoclinic β - LiFeO2 and tetragonal 1.7 wt%. of γ - LiFeO2. The nanocrystalline nature of the prepared samples was confirmed by SEM analysis. The magnetic properties of LiFeO2 showed ferromagnetic property at room temperature.展开更多
文摘Nanocrystalline lithium iron oxide LiFeO2 was synthesized using sol-gel method. Rietveld analysis was performed to confirm the different phases associated in the formation of LiFeO2.
