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
