Abstract: The synthesis of ZnO coated ultrafine TiO2 particles by factional homogeneous method is reported in this paper. The diameter of ZnO crystal is 10.2 nm, and the particle diameter of spherical TiO2 is 40 nm. The influence of the content of ZnO on the coating affection and UV shielding characteristic is investigated. The UV shielding capability of ZnO-coated TiO2 is higher than that of anatase ultrafine TiO2, rutile TiO2 particles and commercial ZnO.

Key words: UV shielding, TiO2 ultrafine podwer, Fractional-homogeneous method, ZnO-coated
