摘　　要：以四氯化钛、氢氧化锂为原料,采用模板法,获得前躯体,再通过煅烧得到纳米钛酸锂。最佳制备工艺条件为模板:钛摩尔比为4∶1,煅烧温度为800℃。对反应机理进行初步研究,证明本工艺得到的前躯体为(Li1.81H0.19)Ti2O5·0.2625TiO2·2H2O,最后生成的产物为Li4Ti5O12。The precursor was prepared by template method with titanium tetrachloride and lithium hydroxide as raw materials, and then to obtain lithium titanate by calcinations. The optimum preparation conditions were that molar ratio was 4：1 of template： Ti, and calcinations temperature was 800℃. The preliminary study on the reaction mechanism prove that the precursor of the process was （ Li1. 81H0.19 ） Ti2 O5 · 0. 2625TiO2 · 2H2 O, and the final product of Li4Ti5O12 was generated.
