钛卤盐热裂解法生产高纯钛的工艺探讨

The study on the process of purifying titanium by thermal decomposition of titanium iodides

对钛卤盐热裂解法生产高纯铁的工艺条件进行了研究。通过正交实验分析，我们得出了铁卤盐热裂解法生产高纯钛的最佳工艺条件：当卤化剂用量在500g左右，基底截面直径为6mm，低温区（卤化源区）和高温区（热裂解区）温度分别控制在500℃左右和1100℃～1200℃之间时，所得产品经电子束熔炼后，纯度可以达到4N8。

This paper analyzed the process of purifying titanium by thermal decomposition of titanium iodides. The optimum technology conditions was obtained by orthogonal experiments . Result： under the condition that the dosing of halogen is 500g or so , the diameter of floor is 6mm, the temperature of source area and decomposition area is 500℃ or so and 1100 - 1200℃ respectively, the purity of production can be 4N8 by EB fusion.
