摘要： 纳米金红石型二氧化钛是一种重要的新型无机功能材料，其制备及其应用在当代愈来愈受到重视．本文利用ZnCO3包覆Ti（OH）4沉淀，500℃预焙解，使ZnCO3转变为ZnO；Ti（OH）4转变为H2TiO3．然后溶去97wt％的包覆ZnO粉体，800℃焙烧，最终制得粒径约20～60nm的金红石型二氧化钛粉体．利用TEM、XRD、ICP对粉体粒子的形貌、大小、物相及化学组成进行了分析．

Abstract: Nanometer rutile TiO2 is a new kind of inorganic functional material. its preparation and application have been paid more and more attention.
In this study, ZnCO3 was used to coat on the surface of Ti(OH)4, then heating to make ZnCO3 transfer to ZnO and Ti(OH)4 transfer to H2TiO3
at 500℃, dissolving about 97wt% coated ZnO powder. Finally ,the rutile TiO2 powders were prepared after having calcined the H2TiO3 powder
(containing 3wt%ZnO) at 800℃, and the particle size was about 20～60nm obtained. The morphology, size, composition of rutile TiO2 powders were studied by
means of TEM, ICP and XRD.

Key words: nanometer rutile TiO2, inoganic functional materials, composite powders
