摘 要: 通过液相共沉淀法对Cr-Co系绿色颜料进行合成和改性研究。采用Cr3+,Cd2+,Zn2+等掺杂手段,研究掺杂粒子种类、数量、晶型结构等对Co,Cr系绿色颜料反射特性的影响;采用合理的烧结工艺,使颜料的光谱反射特性接近于绿色植物。通过热重-差热分析(thermogravimetry-differential thermal analysis, TG-DTA)、傅里叶变换红外光谱(Fourier transform infrared spectroscopy, FT-IR)、扫描电子显微镜(scanning electron microscope, SEM)对引入了掺杂离子的Co,Cr系绿色颜料进行表征。二价阳离子的引入,增大了Co2+ 3d电子层的能级分裂程度,导致作为发色离子的Co2+光学性质变化,最终影响颜料的反射性能。
关 键 词: 特种功能金属材料;绿色颜料;共沉淀法;掺杂离子;红外反射

Abstract: By liquid co-precipitation method, this paper researches synthesis and modification of the Cr-Co-based green pigments. Using Cr3+, Cd2+, Zn2+ and other ion-doped means, it researches the effects of doped particle type, number, crystal structure on reflection characteristics of cobalt, chromium green pigment. Adopting reasonable sintering process, the spectral reflectance characteristics of the pigment are close to green plants. Through thermogravimetry-differential thermal analysis (TG-DTA), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM), the doping ions of cobalt, chromium green pigments are characterized. Introduction of divalent cations, increasing the degree of Co2+ 3d level splitling of the electron shell, results in ion hair color Co2+ optical properties change and ultimately afflect the reflective properties of the pigment.
Key words: special function metallic material; green pigment; co-precipitation method; dopant ions; infrared reflection
