Products of powder metallurgy made of aluminium were investigated by the CPAA method. The microstructure of the samples was supposed to be small spheres (granules) made from pure aluminium with an aluminium oxide layer on their surface. This oxide layer gives the bulk oxygen content of the product. The aim of this work was to determine the oxide layer thickness. The samples were irradiated by 3He2+ particles and the annihilation radiation of the produced 18F isotope was used for oxygen determination. The average diameter of the internal granules was known, so from the measured oxygen concentration it was possible to calculate the average thickness of the above mentioned oxide layer which was found to be 8.5 ± 3 nm.
