A kind of ceramic with a transparent and flat thin film composed by 40 1 00 nm size TiO 2 particles was prepared by sol-gel and dipping methods using Ti（OC 4H 9） 4 as precursor. The film was assembled over the ceramic glaze layer, of which the composition was self developed. The ceramic possesses superhydrophilic, self-cleaning and decontaminating functions. Using methyl orange as organic contaminant, optimum conditions were drawn out for the preparation of the ceramic by investigating the affections of the quantity of Ti（OC 4H 9） 4 , calcining temperature and time and the layers of the films. 光催化 自洁陶瓷 纳米二氧化钛 溶胶-凝胶法 超级亲水性 photocatalysis self-cleaning ceramic nanosized titanium dioxide sol-gel superhydrophilicity TQ174.7 湖北省重大科技攻关项目 （ 991P0 313） 2001-04-01 2021-04-01 4
