Abstract

A new chemical route to synthesize nanostructured lead ruthenium pyrochlore (Pb₂Ru₂O_6.5) powders was developed. The synthesis was performed starting from a metal nitrate aqueous solution and N, N, N′, N′ tetramethylethylendiamine (TMEDA). The amine, which is a mild basic chelating agent, was able to control the simultaneous precipitation of lead and ruthenium oxo/hydroxides. For the sake of comparison, Pb₂Ru₂O_6.5 powders were prepared using the more conventional polymeric precursor method. The new method was effective for the synthesis of nanostructured Pb₂Ru₂O_6.5 powders already stable at 400°C and up to 1000°C.
