摘要
矿化剂直接影响颜料的合成温度和颜料的呈色性能,本文通过掺杂四种不同矿化剂:Na F、Na Cl、H3BO3和Na2HPO4,改变灼烧温度,制备出黄色颜料Sm0.3Ce0.66Mo0.04O(1.85+δ),用XRD表征其晶体结构,用CIE颜色系统—L*a*b*(1976)色空间体系和紫外可见反射光谱分析其光学性能,结果表明,制备出的黄色颜料均属于立方萤石结构,以H3BO3为矿化剂时,得到鲜艳的黄色颜料,并随灼烧温度升高,反射光谱吸收边发生红移,颜料颜色由淡黄色变为亮黄色。
Yellow pigments of Sm0. 3Ce0. 66Mo0. 04O（1. 85 ＋ δ）were prepared by doping four mineralizers such as Na F,Na Cl,H3BO3 and Na2HPO4and changing calcination temperature. Their crystal structure were characterized by XRD. Their optical properties were analyzed by the CIE 1976 L＊a＊b＊colorimetric scales and UV-vis reflectance spectroscopy. The results show that the yellow pigments belong to the cubic fluorite structure. The brilliant yellow pigment were prepared when the mineralizer was H3BO3. The reflection absorption edge was red shifted and the colour of pigment changed from yellowish to bright yellow as increasing calcination temperature.
