Abstract Platinum rhodium alloy (PtRh20) powder was prepared in pure aqueous medium by spark plasma. The impurity content, surface morphology, composition and particle size distribution of the powder were analyzed by ICP, SEM and laser particle size analyzer. The results show that the efficiency of PtRh20 alloy powder prepared by electrospark plasma erosion method is up to 1 000 g/h, and the purity of the powder is high. It is composed of high spherical particles and floccules with the same composition. The particle size of the powder is basically between 5-60 μm, and the average particle size is 25 μm.
