Abstract XPS and AES have been applied to the surface analysis of antimony oxides, Sb 2 O 3 , Sb 2 O 4 and Sb 2 O 5 . By means of the computer‐operated separation of oxygen and antimony contribution, the oxygen to metal atomic ratios calculated from XPS data were found to be close to the expected values. An antimony powder sample was found to be covered by a surface layer of Sb 2 O 4 and the variations in shape of Auger MNN peaks of Sb during depth profiling are shown and discussed.
