分析了卤化法高纯钛制备过程中铝的来源。试验条件下,杂质元素铝能在卤化源区(798~998 K )与卤化剂反应,生成A lI3和A l2 I6;在沉积区(1473~1673 K ),铝的碘化物分解而污染高纯钛的行为可被有效抑制。结合热力学计算和试验结果,分析了高纯钛中杂质铝的来源。
分析瞭滷化法高純鈦製備過程中鋁的來源。試驗條件下,雜質元素鋁能在滷化源區(798~998 K )與滷化劑反應,生成A lI3和A l2 I6;在沉積區(1473~1673 K ),鋁的碘化物分解而汙染高純鈦的行為可被有效抑製。結閤熱力學計算和試驗結果,分析瞭高純鈦中雜質鋁的來源。

The source of Al in high purity titanium preparad by halide process was analyzed .Under the experiment conditions ,the impurity Al can react with halogen agent to generate AlI 3 and Al2 I6 in the halide source area(798-998 K) .In the deposition area(1 473 -1 673 K) ,the behavior of aluminium polluting high purity titanium as impurity because of decomposition of aluminium iodides can be avoided .The source of aluminium in the high purity titanium is analyzed by thermodynamic calculation and experimental results .
