摘要
本文研究了在不同结晶条件下制备得到的一系列KF-AlF3共晶产物。使用差热分析法(DTA)测定了这一系列产物的熔点,使用X-射线衍射仪(XRD)确定了各生成物的组成。试验表明,在反应过程中,将结晶温度控制在特定条件下有利于得到主结构为K2A1F5·H2O的氟铝酸钾共晶材料。该材料为铝及铝合金钎焊过程应用的理想状态铝钎剂。
A series of KF-AlF_3 eutectic products were prepared at different eutectic conditions. The melting points of the products were measured by differential thermal analysis(DTA) and the composites of each products were confirmed by X-ray diffraction. It was suggested that it is good to produce K_2AlF_5·H_2O, an ideal fluxe, at a certain temperature.
