摘要

采用溶胶-凝胶法制备了纳米晶氧化铁锂LiFeO2。Rietveld分析证实了不同相与LiFeO2的形成有关。定量Rietveld细化表明，样品中含有:立方相α - LiFeO2 39.9%，单斜相β - LiFeO2 58.5%，四方相1.7 wt%。γ - LiFeO2通过扫描电镜分析证实了所制备样品的纳米晶性质。LiFeO2的磁性能在室温下表现为铁磁性。

Rietveld Refinement of Nanocrystalline LiFeO 2 Synthesized by Sol-Gel Method and Its Structural and Magnetic Properties

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. 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.
