采用醇盐水解法，控制醇盐和水的摩尔比和水解的速度等条件，可以制备出５～２０ｕｍ左右的纳米氧化钛粉体．用乙醇洗涤以后，沉淀物转变为无定形；而在乙醇洗涤以前用醋酸处理过的粉体为晶体结构（锐钛矿结构）．不同的处理方法对二氧化钛粉体团聚的影响不同，ＸＲＤ、ＢＥＴ、ＤＴＡ－ＴＧ和ＴＥＭ的研究结果表明，在一定的条件下，经醋酸处理过的粉体表现出优良的性能，晶粒尺寸小，团聚度低，而且失重小，在较低的温度下就进行由锐钛矿向金红石的转变．粉体的这些性能直接影响到材料的烧结特性．
The alkoxide hydrolysis method, controlling the molar ratio of alkoxide to water and the hydrolysis rate and other conditions, can be prepared about 5 ~ 20um nano titanium oxide powder. After washing with ethanol, the precipitate turned to amorphous; whereas, the acetic acid-treated powder had a crystal structure (anatase structure) before ethanol washing. The effects of different treatment methods on the agglomeration of TiO2 powder are different. The results of XRD, BET, DTA-TG and TEM show that under certain conditions, the acetic acid treated powder shows good performance and the grain size is small , Low reunion, and less weight loss, at a lower temperature from anatase to rutile transformation. These properties of powder directly affect the sintering characteristics of the material.
