  • Abstract
    It is shown that positron annihilation lifetime spectroscopy is a quite promising tool for nanostructural characterisation of humidity-sensitive spinel-type MgAl2O4 ceramics, the results being achieved provided four-component fitting procedure with arbitrary lifetimes is applied to treat mathematically the measured spectra. It is shown that Tao-Eldrup model is adequate for calculation of nanopore size in MgAl2O4 ceramics using lifetime values of the third and four components.
