Resumen

VILLICANA, M.; GARNICA-ROMO, M. G.; PEREZ-ROBLES, J. F.  y  CORTES, J. A.. A new process to obtain palladium as metal powders from salts: thermodynamic an kinetic study. Lat. Am. appl. res. [online]. 2007, vol.37, n.2, pp.115-120. ISSN 0327-0793.

In this work, a new process to obtain palladium powders from their salts by using a cementation process (in aqueous solution) through an iron electrode and a catalyst agent was studied. The process gives results that in practice can also be applied to obtain bulk metal from secondary sources. Nano and micrometric particles could be obtained from this new process. The physicochemical and morphological characteristics of these powders are heavily dependent on the method used for their production. For the Palladium test and PdCl2 solution 0.093 M, a minimum quantity of catalyst agent was added to accelerate the reaction. In the palladium powders only small round particles were obtained, which can be easily suspended in solution. For the reaction, there is no considerable temperature dependence. Thus, the process can be carried out at room temperature resulting in considerable energy saving.

Palabras clave : Palladium Metal Powder; Nanometric Particles; "Black" Palladium Powder.
