以Bi（NO3）3·5H2O和NH4VO3为原料，利用化学沉淀法制备了BiVO4黄色颜料，并系统地研究了不同反应条件如：反应物初始浓度、溶液pH值、反应温度和反应时间对粒径和颜色的影响．采用扫描电子显微镜对产品进行了表征，得出如下结论：用化学沉淀法制备钒酸铋，粒子粒度较小，均匀性好．同时得到的钒酸铋是一种颜色鲜艳、无毒的高级无机黄色颜料．

Using Bi （NO3）3·SH2O and NH4VO3 as raw materials,BiVO4 yellow pigment was prepared by chemical precipitation method. The influenence of reaction concentration,the value of pH, reaction temperature and reaction time on the particle size and colour was investigated. The scanning electron microscope was used to characterize the samples. The conclusion is that BiVO4 yellow pigment obtained by this way has smaller particles size and a good homogeneity. It is a bright, poisonless and high-grade inorganic yellow pigment.
