Study of nanoporous in humidity-sensitive MgAl₂O₄ ceramics with positron annihilation lifetime spectroscopy
It has been shown that positron annihilation lifetime spectroscopy is a quite promising tool for nanostructural characterization of humidity-sensitive spinel-type MgAl₂O₄ceramics. The results have been achieved using the four-component fitting procedure with arbitrary lifetimes that is applied...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | It has been shown that positron annihilation lifetime spectroscopy is a quite
promising tool for nanostructural characterization of humidity-sensitive spinel-type
MgAl₂O₄ceramics. The results have been achieved using the four-component fitting
procedure with arbitrary lifetimes that is applied to mathematically treat the measured
spectra. It has been shown that the Tao-Eldrup model is adequate to calculate the
nanopore size in MgAl₂O₄ ceramics if using the lifetime values of the third and fourth
components. |
