溶胶-凝胶法制备陶瓷喷墨打印用镨锆黄色料
Preparation of Zirconium Praseodymium Yellow Pigments for Ceramic Inkjet Printing by Sol-gel Method
摘要
Abstract
Pr-Zircon yellow pigment with small particle size and good homogeneity was prepared by a sol-gel method. Based on the colorimetric evaluation according to the CIEL*a*b* color system, the sample was obtained under optimum condition (i.e., adopted Pr of 3%, solution pH value of 3 and a bath-temperature of 70℃). The colorimetric parameters of optimal sample are the lightness of 90.37, yellow-blue value of 40.50, red-green value close to 0 (-0.33), indicating a pure yellow color with less interference of red-green color. The results by X-ray diffraction show that the sample contains zirconium silicate as a major phase with a small amount ofβ-quartz and monoclinic zirconia. The analysis by transmission electron microscopy reveals that Zr ions in zirconium silicate are partially substituted by Pr ions, the grain size of well-grown crystal is 62 nm, and a tetragonal structure with clear crystal stripes appears. According to the analysis of decoration effect of prepared inks, Pr-Zircon yellow pigment has a pure yellow color glaze effect.关键词
