摘　　要：采用钛酸丁酯水解制备了单分散的TiO_(2)微球,以球状TiO_(2)为核,通过尿素均相沉淀法制备了具有核壳结构的钛黄色料,研究了核壳结构的构建对(Cr,Sb)TiO_(2)色料的近红外反射特性的影响。结果表明,通过球壳结构的构建可提高(Cr,Sb)TiO_(2)的近红外反射率,核壳结构的TiO_(2)@(Cr,Sb)TiO_(2)可作为一种具有近红外反射特性的黄色功能陶瓷色料。Monodisperse TiO_(2)microspheres were prepared by hydrolysis of butyl titanate.With spherical TiO_(2)as the core,a titanium yellow material with a core-shell structure was prepared by the urea homogeneous precipitation method.The average near-infrared reflectance of the(Cr,Sb)TiO_(2)sample is higher than that of TiO_(2)@(Cr,Sb)TiO_(2)sample.The core-shell structured TiO_(2)@(Cr,Sb)TiO_(2)powder can be used as a yellow functional ceramic pigment with near-infrared reflection characteristics.
