Abstract: The influence of different reducing and dispersing agents and concentration of Palladic solution on the properties of ultrafine palladium powder products has been studied. The technological Process of ultrafine palladium powder has been decided. The ultrafine palladium powder produced by such process has a recovery ratio of 98.2%~98.6% and the property is up to the level of Degussa 4 type ultrafine palladium powder produced in Germany. The results in application is good.
