项目摘要
In this investigation, new, continuous titanium production route has been research, whereby the titanium has been obtained by reacting molten MgCl2-TiCl2 mixed salt reduction by Mg via repetition method. The repetition method is to repeat the following chlorination step (a) and the reduction step (b), in turn, thus increasing Ti product quantity in a same reactor :Ti(s)(in MgCl_2(l)) +TiCl_4 (g) = TiCl_2-MgCl_2 (a)TiCl_2-MgCl_2(l)+Mg(l)= Ti(s) + MgCl_2(l) (b)1. Thus, main purpose of this investigation is to find the followings :(1) reactivity of Ti and TiCl4 in molten MgCl2(2) TiCl2 and TiCl3 formation in the mixed salt(3) Ti separation from MgCl2 after the deduction(4) Ti product morphology and purity2. The experimental observation are as follows :(1) appropriate experimental conditions making this repetition route successful has been sought whereby no un-reacted TiCl4 is observed in reaction (a)(2)TiCl3 formation was minimized by Ar bubbling after the chlorination whereby reduction of TiCl3 takes place by reaction with Ti in the mixed salt(3) Ti product morphology shows that they are powdery, of 100〜200μm sintered grain, and granular, of 100μm columnar. Ti purity was around 85.6 %
本文研究了一种新的连续钛生产路线,即通过熔融MgCl_2-TiCl_2混合盐反应,经Mg还原,通过重复法获得钛。重复方法是依次重复以下氯化步骤(a)和还原步骤(B),从而增加同一反应器中的Ti产物量:Ti(s)(在MgCl_2(l)中)+TiCl_4(g)= TiCl_2-MgCl_2(a)TiCl_2-MgCl_2(l)+Mg(l)= Ti(s)+ MgCl_2(l)(B)1。因此,本研究的主要目的是发现以下几点:(1)Ti和TiCl_4在熔融MgCl_2中的反应性(2)混合盐中TiCl_2和TiCl_3的形成(3)扣除后Ti与MgCl_2的分离(4)Ti产品的形貌和纯度2。实验观察结果如下:(1)已经寻找了使该重复路线成功的适当实验条件,由此在反应(a)中没有观察到未反应的TiCl 4;(2)氯化后通过Ar鼓泡使TiCl 3的形成最小化,由此通过与混合盐中的Ti反应而发生TiCl 3的还原;(3)Ti产物形态显示它们是粉末状的,100 μ m至200μm的烧结颗粒,和颗粒状的,100μm的柱状。钛的纯度约为85.6%
