摘要：
本发明公开了一种结晶型二氧化硅包裹型γ～Ce2S3红色色料，由结晶型二氧化硅基体、以及包覆在基体内的γ～Ce2S3色料颗粒构成；所述每个结晶型二氧化硅基体内镶嵌有二个或二个以上γ～Ce2S3色料颗粒。此外，还公开了上述结晶型二氧化硅包裹型γ～Ce2S3红色色料的制备方法和制得的产品。本发明包裹型γ～Ce2S3红色色料以结晶型二氧化硅为包裹体，包裹完全、包裹层致密，具有优异的抗酸腐蚀和抗高温氧化性能；本发明通过酸、碱分步催化溶胶-凝胶法进行制备，过程操作简单、包裹效率高，并且能够很好地适应环境友好及清洁生产的发展趋势，有利于二氧化硅包裹型γ～Ce2S3色料产业化生产及其技术的发展和推广。
摘要（英）：

The invention discloses crystalline silicon dioxide wrapped gamma-Ce2S3 red pigment. The crystalline silicon dioxide wrapped gamma-Ce2S3 red pigment is prepared from crystalline silicon dioxide base bodies and gamma-Ce2S3 pigment particles wrapped with the base bodies; and the two or more gamma-Ce2S3 pigment particles are inlaid in each crystalline silicon dioxide base body. In addition, the invention further discloses a preparation method of the crystalline silicon dioxide wrapped gamma-Ce2S3 red pigment and a prepared product. The wrapped gamma-Ce2S3 red pigment adopts crystalline silicon dioxide as a wrapping body, wrapping is complete, a wrapping layer is compact, and the wrapped gamma-Ce2S3 red pigment has excellent acid corrosion resisting and high-temperature oxidation resisting properties; and the wrapped gamma-Ce2S3 red pigment is prepared through an acid and alkaline stepped catalysis sol-gel method, the process is easy to operate, the wrapping efficiency is high, the wrappedgamma-Ce2S3 red pigment can well adapt to the development tendency of environmental friendliness and clean production, and industrial production of the crystalline silicon dioxide wrapped gamma-Ce2S3red pigment and development and popularization of the technology of the crystalline silicon dioxide wrapped gamma-Ce2S3 red pigment are facilitated.
