Abstract

Nanoporous spinel‑type MgAl2O4 ceramics sintered at 1100 and 1400 °C, considered as promising materials for humidity sensors, were investigated using positron annihilation lifetime spectroscopy (PALS). It is demonstrated that PALS can be applied to study both positron trapping in bulk defects and moisture absorption processes (“pick‑off” o‑Ps annihilation) in nanopores filled with adsorbed water
