摘要
采用不同原料及工艺制备TiO_2胶体,考察了几种因素对TiO_2胶体稳定性和结构性质的影响。研究结果表明,在一定条件下,以钛酸四丁酯为原料,经硝酸处理所制得的胶体比较稳定,粉体失重小,并能在很宽的温度范围内保持锐钛矿型晶体结构。
TiO2 Sols were prepared by different materials and methods. The influences of preparation parametves on the properties of TiO2 Sols have been studied systematically. The results show that the properties of TiO2 sols,formed from Ti(OBu)4with nitric acid treatment,are better, and the crystal is of anatase structure over a relative wide temperature range under certain conditions.
