【摘要】 本文采用淬冷法、差热分析（DTA）及X衍射分析（XRD）技术,确定了Na₃AlF₆—AlF₃二元系蒸气冷凝物的组成,研究了该二元系NaF与AlF₃分子比为1.0成分处的物相组成,并鉴定出化合物NaAlF₄的存在,确定了该化合物稳定存在的温度范围为550～707℃。更多还原

【Abstract】 The vapor constitution over the molten mixture of Na₃AlF₆ and AlF₃, and the phase constitution of a mixture of 44.44% AlF₃ and 55.56% Na₃AlF₆ （by weight）were studied by quenching method, XRD and DTA. A new compound NaAlF₄ was identified in the Na₃AlF₆-AlF₃ system, the existence temperature range of NaAlF₄ was determined to be 550-707℃.更多还原
