Abstract

Spherical Ag-Pd alloy particles were prepared from an aqueous solutions of AgNO₃ and Pd(NO₃)₂ by ultrasonic spray pyrolysis. As-prepared powders were dense and non-agglomerated particles, and had sub-micron size and narrow size distribution. XRD shows that as-prepared particles are polycrystalline and that the crystal phase of the as-prepared particles has an alloy composition. Ag-Pd alloy particles obtained from spray pyrolysis offer superior oxidation-resistivity of Pd and specific resistivity as compared with those obtained from coprecipitation.
