摘要

通过加热KZrF5的水悬浮液制备氧化氟锆酸盐K2Zr3OF12。采用热分析（DTA-TG）、x射线粉末衍射（XRD）、红外光谱（IR）和拉曼光谱（Raman）对其结构和热分解进行了研究。在620℃下，K2Zr3OF12完全水解分解主要生成单斜相K2ZrF6和ZrO2的混合物。对氧化氟锆酸盐K2Zr3OF12及其加热产物的实验红外光谱和拉曼光谱进行了测量、整理和分析。实验光谱中的波段是根据量子化学计算的结果分配的。

Structure and Thermal Behavior of Potassium Oxofluorozirconate K2Zr3OF12

Oxofluorozirconate K₂Zr₃OF₁₂ was prepared by heating an aqueous suspension of KZrF₅. Its structure and thermal decomposition were studied by thermal analysis (DTA–TG), X-ray powder diffraction (XRD), IR and Raman spectroscopy. The complete hydrolytic decomposition of K₂Zr₃OF₁₂ at 620°C mainly yields a mixture of monoclinic K₂ZrF₆ and ZrO₂ phases. Experimental IR and Raman spectra of oxofluorozirconate K₂Zr₃OF₁₂ and its heating products were measured, systematized, and analyzed. The bands in the experimental spectra were assigned based on the results of quantum-chemical calculations.
