摘　　要：采用液相沉淀法,通过表面活性剂进行分散,制备了-βCuSCN纳米粉体。讨论了反应温度、反应物浓度及表面活性剂对粉体的影响,用X射线衍射(XRD)、透射电镜(TEM)和激光粒度分析仪对粉体进行了表征。结果表明,最佳反应温度为80℃,最佳反应物浓度均为0.2 mol/L;当聚乙二醇400(PEG400)添加量为1.5%时,分散效果最好,制备的粉体平均粒径为40 nm左右。β-CuSCN nano powders were prepared by liquid precipitation method, and were dispersed by surfaetant. The influence of temperature, concentration and surfactant on the particles was investigated with X-ray diffraction analysis （XRD）, transmission electron microscope （TEM） and Laser Particle Sizer. The results showed that the optimal temperature is 80 ℃, the optimal concentration of all reactants is 0.2 mol/L. The better dispersion was observed and the grain size is about 40 nm when the amount of polyethylene glycol 400 （PEG400） was 1.5%.
