摘要
在充分回收含锡阳极泥有价金属的基础上,采用从锡锑二次资源中直接提取的高纯氯锡酸铵和氯氧锑为原料,合成了性能优良的纳米级锑掺杂二氧化锡(ATO)粉。针对液相共沉淀法制备ATO的过程中,锡和锑的水解不同步从而未能实现真正共沉淀掺杂的问题,以(NH4)2SnCl6和Sb4O5Cl2为原料,采用配合共沉淀法,考察了反应过程中的pH、反应温度、掺锑浓度、煅烧温度、前驱体洗涤次数和分散剂种类等对ATO粒度和形貌的影响,确定了最优化条件,即:滴定终点pH=3,反应温度60℃,锑掺杂浓度10%(质量分数),热处理温度600℃,前驱体洗涤次数为6次,采用分散剂c,并进行了实验验证。
Based on the fully reclaiming of the valuable metal, pure (NH_4)_2SnCl_6 and Sb_4O_5Cl_2 were directly extracted form tin anode slurry, by using Sb_4O_5Cl_2 and (NH_4)_2SnCl_6 as precusors, fine antimony doped tin oxide(ATO) powder with excerllent performance was prepared by complex-co-precipitation, which can resolve some traditional problems when preparing ATO powder, such as conglomeration; limited material, expen sive cost and, etc. Especially, this method can make Sn^(4+) and Sb^(3+) hydrolyze at the same speed and get more even doped tin oxide. The optimal experimental condition is as: terminal pH value, reactive temperature 60℃, Sb doped concentration is 10%, heat treating temperature is 600℃, wash time is 6, and using dispersant c.
