Abstract	It is established that positron annihilation lifetime spectroscopy can be successful used as porosimetry method to study of nanopores size and transformation of free volume in humidity-sensitive MgO-Al2O3 ceramics in adsorption-desorption cycles using lifetimes of ortho-positronium-related components. It is shown that the fourth component gives information about water-free volume or nanopores size, while the third component reflects positronium trapping both in nanopores and in water “bubbles”.
