采用溶胶-凝胶法，制备了二氧化铈包覆金红石型钛白粉颗粒。采用罗丹明 b 紫外老化实验法，研究了氧气、表面包覆结构、表面包覆量以及铈、硅和锆无机盐氧化物对金红石型钛白粉耐候性的影响。结果表明，致密均匀的铈氧化物表面包覆能改善金红型钛白粉的耐候性，阻隔与周围氧气的接触；当铈氧化物包覆量为3％时，金红石型钛白粉的耐候性最好；铈氧化物比硅、锆无机盐氧化物能更好的改善金红石型钛白粉的耐候性能。
The CeO2-coated rutile TiO2 were prepared by sol-gel method.The influence of oxygen,microstruc-ture,amount of surface coating and cerium,silicon and zirconium inorganic oxide on rutile TiO2 weatherability were studied by rhodamine b ultraviolet aging test method.The results showed that dense and uniform cerium oxide surface coating can improve the rutile TiO2 weatherability and cut off contact with the oxygen around;ru-tile TiO2 coated 3% cerium oxide have the best weatherability;cerium oxide can better improve the rutile TiO2 weatherability than silicon and zirconium inorganic oxide.
