摘　　要：本文研究了HN分散剂、稀土氧化物CeO2 、超声处理工艺等对超细TiO2 水系料浆分散性的影响。结果表明 ,通过加入 0 .2 5 %HN分散剂和 0 .1%稀土CeO2 ,以及 30分钟的超声处理 ,获得了平均颗粒尺寸约为 10 0nm的高分散料浆 ,其粉末比表面积提高 2 .8倍。并且实验中还用分散处理得到的悬浮料浆成功地制备了TiO2 薄膜。In this paper, the effects of HN dispersing agent, rare-earth oxide CeO 2, ultrasonic treatment were studied on the dispersivity of water system TiO 2 mud. The results showed that high-dispersivity mud was obtained with the grain size of about 100nm by the addition of 0.25%HN dispersing agent and 0.1% CeO 2 after 30min ultrasound dispersing. The BET value of the dispersed powder was 2.8 times than that of the no-dispersed powder. At the same time the TiO 2 film was prepared using the suspending mud successfully.
