以Ti-6Al-4V钛合金和FeCl2·4H2O为出发原料模拟工业金属钛废料和工业氯化废弃物,在中高温条件下(配合真空),通过氯化法回收金属钛废料中的钛,获得金属钛的工业生产原料(TiClx).通过XRD、SEM/EDS和化学分析等检测手段对实验产物的物相、形貌和转化率等进行分析.结果表明,利用工业氯化废弃物回收废金属钛在技术上是可行的;当反应温度为1200K、反应时间为2h时,物料的转化率可达到80%以上.利用工业氯化废弃物回收废金属钛既减少资源的浪费又避免了氯化废弃物的污染、且有价金属回收完全,具有良好的工业应用前景.
Ti-6Al-4V titanium alloy and FeCl2 · 4H2O are taken as starting materials to simulate industrial titanium scrap and industrial chlorinated waste, and the titanium in the titanium scrap was recovered by chlorination under medium-high temperature (with vacuum) to obtain The industrial production of titanium (TiClx) was analyzed by XRD, SEM / EDS and chemical analysis, etc. The results showed that the recovery of scrap metal from industrial chlorinated waste Titanium technically feasible; when the reaction temperature is 1200K, the reaction time is 2h, the material conversion rate can reach more than 80%. The use of industrial chlorinated waste recovery of titanium scrap metal both to reduce waste of resources and to avoid the chlorination Waste pollution, and complete recovery of valuable metals, has good prospects for industrial applications.
