液相法制备锆钒蓝色料的研究

A STUDY ON THE PREPARATION OF TURQUOISE PIGMENTS BY THE LIQUID PHASE METHOD

介绍了以正硅酸乙酯 (Si(C2 H5O) 4)、氧氯化锆 (ZrOCl2 )和氧氯化钒 (VOCl3)等为原料 ,以水和乙醇为介质制备V -ZrSiO4 蓝色料超细粉的方法。其中钒均匀地分散固溶在ZrSiO4 中 ,通过系统改变Zr Si(摩尔比 )和V的固溶量可获得最佳呈色效果。通过XRD、DTA -TG和红外光谱的测试和分析明确了在加热过程中颜色变化与钒在ZrSiO4 中固溶量的关系 ,及V4 +取代ZrSiO4 中部分Zr4 +形成固溶体的结论。

In this paper,a method on the preparation of ultra fine turquoise pigments powders using TEOS、ZrOCl 2、and VOCl 3 as materials in water and ethanol mediums was presented.Vanadium was homogeneously dispersed in ZrSiO 4 and solid solution was formed.By systematically changing the Zr/Si(molar ratio)and the solid solution amount of Vanadium,the optimal color development effect can be obtained.By SEM、DTA-TGA and the infrared ray spectrum test and analysis,the relationship of color development of samples during heating with the solid solution amount of Vanadium in ZrSiO 4 was obtained and it was concluded that V 4+ partly displaced Zr 4+ in ZrSiO 4 to form solid solution.
