Abstract: 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.

Key words: lead tungstate; deposition; nano-partic
