Mechanical alloying is a high energy ball-milling technique nowadays used for preparing powders of equilibrium and non-equilibrium compounds. The new products that can be prepared by this technique, however, suffer from possible contaminations coming from both milling tools and milling atmosphere. This fact, if not considered, may lead to misunderstandings of the mechanical alloying process. We report in this paper on the effect of oxygen contamination in the solid state reaction between palladium and silicon. The investigation has been carried out by x-rays, XPS and Auger spectroscopy performed on Pd80Si20samples milled with both planetary and shaker mills.
