DOI: 10.3969/j.issn.1671-7627.2003.02.006, PP. 27-31
Keywords: 四钛酸钾,衍生物,离子交换,水合,热力学平衡模型
Abstract:
利用四钛酸钾(k2ti4o9)离子交换平衡热力学模型预测了获得k2ti4o9纯相衍生物的最优条件,并以k2ti4o9晶须为前驱体,以目标产物的固相ti与k摩尔比为控制目标,通过调节离子交换过程中溶液平衡ph值和用k+选择性电极控制液相k+浓度,成功合成出纯相的水合四钛酸h2ti4o9*1.2h2o、tio2晶须、k2ti8o17晶须、k2ti6o13晶须,用实验验证了预测的准确性.同时实验结果表明,只要控制了离子交换中间产物的固相化学组成,就可以控制最后产物的形式,初步探索了反应过程中组成和结构的关系.
