摘要：

以钨酸钠和硝酸铅为原料,以聚乙二醇200为分散剂,用沉淀法配制出钨酸铅混浊液。将钨酸铅混浊液在100℃烘干后,制备出钨酸铅纳米粉体。对制备的样品进行X射线衍射分析,结果表明:钨酸铅纳米粉体结晶良好。将制备的样品在不同温度退火后,用透射电镜分析了其形貌,结果表明:钨酸铅纳米粉体的颗粒粒度随着退火温度的升高而增大。

Lead tungstate nano-particles were prepared by deposition after being heat-treated at 100 ℃, using lead nitrate and natrium tungstate as starting materials and polyglycol 200 as dispersant. The XRD pattern indicates that the well crystalized lead tungstate nano-particles were obtained under the given synthesis conditions. The prepared nano-particles were heat-treated at different temperatures. Transmission electron microscopy was used to study their morphologies. The results show that the sizes of nano-particles increase with the increaseing of annealing temperatures.
