Mass Spectrometry of the Laser Desorption/Ionization of Magnesium, Tungsten, and Boron Powders before and after Mechanochemical Activation

Abstract

Abstract Powders of boron, magnesium and tungsten before and after mechanochemical activation are studied via laser desorption/ionization. It is found that the activation process removes low molecular weight hydrocarbon impurities and high molecular weight clusters of oxides and hydroxides. It is shown that this technique allows determination of clusters in a wide range of masses.
