摘要: 通过中温水热法合成出复合氟化物Li2BeF4,并对合成中反应物的配比、反应温度和反应时间等条件进行了研究.XRD测试结果表明产物物相纯净,SEM显示产物为250μm的六方柱形晶体;IR和XPS测试表明产物中羟基和氧含量低.实验发现了晶化曲线的振荡现象,并做了初步的解释.

关键词: 复合氟化物, 中温水热合成, Li2BeF4

Abstract: The complex fluorides Li2BeF4 have been hydrothermally synthesized at 140-200 and characterized by XRD, IR, SEM And XPS. The hydrothermal conditions such as reaction temperature, reaction time, and the ratios of initial composition were investigated. The vibrations of crystallization curves were observed.
