本研究是对过渡金属在铝熔体中溶解动力学一系列研究工作[1,2]的继续。使用的原材料是碘化锆MPTY95—67—66和纯铝A995,ΓOCT 11069—64。初步试验表明,锆圆盘试样于700℃在铝熔体中进行溶解,试样转速为16.67弧度/秒,历时1小时,锆完全转变为铝氧石分散到铝基体中,试样初始的圆柱状保持不变。其原因是,形成锆铝氧石的速度比锆在铝熔体中溶解的速度快得多。所得到的试样在5%NaOH溶液中溶解后,根据化学分析和X射线分析资料查出,有与
This study is a continuation of a series of studies on the kinetics of the transition metal dissolution in aluminum melt [1,2]. The raw materials used are zirconium iodide MPTY 95-67-66 and pure aluminum A995, ΓOCT 11069-64. Initial tests showed that the zirconium disk samples were dissolved in aluminum melt at 700 ℃ and the sample rotation speed was 16.67 rad / s. After 1 hour, the zirconium completely transformed into aluminum oxide dispersed into the aluminum matrix. The initial Cylindrical remains unchanged. The reason for this is that zirconium aluminosilicate forms much more rapidly than zirconium dissolves in the aluminum melt. The obtained sample is dissolved in 5% NaOH solution, and then is found on the basis of chemical analysis and X-ray analysis data.
