Mechanochemical preparation of palladium chalcogenides

Palladium chalcogenides of PdS, Pd17Se15, PdSe2, PdTe, Pd3Te2 and PdSeTe were prepared by milling elemental mixtures, using a planetary-type ball mill at room temperature. These chalcogenides were obtained within 30 min. Pd17Se15 was also obtained when the elemental mixture was immersed in methanol or ethanol at room temperature for 10 days.
