摘　　要：采用醇盐的乙醇溶液,制备了纳米锐钛矿相二氧化钛粉体.通过TEM和XRD分析测试手段,对所得粉体进行了表征.TiO2粒子外观呈球形,粒径为5～10 nm.用此制备工艺新技术,操作简单,无污染,易于实现工业化.Nanometeral anatase titanium dioxide powders were prepared by hydrolysis of titanium-tetrabutoxide with ethanol in this passage. The ultrafine powders were characterized by TEM and XRD techniques. The experimental results show that the TiO2 particles prepared are rutile, spherical and nanometer. The main particle size is between 5nm and 10nm. The new technology is simple to operate without pollution and is easy to be industrialized.
