采用溶剂热法在180 ~ 240℃下合成了配合氟化物li2bef4和lisralf6，并用x射线粉末衍射（XRD）、扫描电镜（SEM）、热重分析（TGA）、红外光谱（IR）和x射线光电子能谱（XPS）对其进行了表征。考察了溶剂、初始混合物的摩尔比、反应温度和反应时间等因素对反应的影响。实验结果表明，采用溶剂热法制备li2bef4和lisralf6粉体是可行的。
The complex fluorides Li2BeF4and LiSrAlF6were synthesized solvothermally at 180–240 °C and characterized by means of X-ray powder diffraction (XRD), Scanning electron microscopy (SEM), thermogravimetric analysis (TGA), infrared spectroscopy (IR) and X-ray photoelectron spectroscopy (XPS). The different influence factors such as solvents, molar ratios of initial mixtures, reaction temperature and reaction time were investigated. The experimental results indicated that Li2BeF4and LiSrAlF6powders could be controllably synthesized in the solvothermal process.
