摘　　要：通过固相煅烧法制备钒酸铋颜料,研究反应原料、煅烧温度及煅烧时间对产品物相、粒度及比表面积、颜料呈色性能等的影响。结果表明:以NH4VO3及Bi(NO3)3·5H2O为反应原料,制备条件更温和;煅烧温度为500℃、煅烧时间为12 h,制备出的钒酸铋产品物相纯度较高、平均粒径及比表面积处于较优水平,产品对应的色坐标为L*=84.91,a*=1.18,b*=85.87,c*=85.88,颜料呈色性能优于市售钒酸铋颜料。Bismuth vanadate pigment was synthesized by solid-state reaction, and the influences of raw materials, calcination temperature and time on the phase compositions, particle size, specific surface area and chromatic property of the obtained bismuth vanadate were investigated in this paper. It is indicated that a more moderate preparation condition can be satisfied using NH4VO3 and Bi（ NO3 ）3 · 5H2O as raw materials. Bismuth vanadate possessing a higher phase purity, more excellent particle size distribution and specific surface area can be obtained by calcination at 500 ℃ for 12 h ,with a chromaticity coordinates of L^＊ = 84.91 ,a^ ＊ = 1.18 ,b ^＊ = 85.87 and c ^＊ = 85.88 for the product demonstrating a superior pigmentary performance to the bismuth vanadate sold around the market.
