Abstract (en)
Alkaline aqueous electrolytes for the electrodeposition of palladium comprising a soluble palladium compound, one or more complexing agents of an organic compound containing a heterocyclic ring having one or more nitrogen atoms in the ring position, at least one carboxyl group substituted on a ring carbon, and at least one hydroxyl or carbonyl oxygen attached to a ring carbon. The palladium compound and complexing agents are soluble in the electrolyte. Optionally, one or more soluble alloying metal compounds can be added to the electrolyte when palladium alloys are to be electrodeposited therefrom. Also, methods for formulating these electrolytes and for electrodepositing palladium or palladium alloys therefrom.
