Influences of the starting salts on the phase and morphology of the Pb(Zr, T)O$_3$powders prepared by ultrasonic spray pyrolysis were studied. The Phases of the Powders Prepared from the combination of metal nitrate(or oxynitrate), acetate(or oxyacetate), and alkoxide were the Pb(Zr, Ti)O$_3$with or without minor PbTiO$_3$. The pores on the surface of the spherical particles increased with the nitrate content in the starting solution and their formation was thought to result from the decomposition characteristics of metal nitrate. Pb acetate, Zr oxyacetate, Ti oxynitrate, and Ti (isopropoxide+acetylacetonate) was suitable as the starting salts for the preparation of Pb(Zr, Ti)O$_3$powders by ultrasonic spray pyrolysis in the viewpoint of the phase and morphology of the powders.
