Radiation stability of powders in mixtures with Al2O3 nanoparticles

A comparative research was conducted to investigate the absorption spectra of barium titanate powders mixtures with aluminum oxide micro- or nanopowders irradiated by electrons. It was established that the addition of aluminum oxide nanopowder enhances the radiation stability of mixtures, which increases with the concentration of nanoparticles. Stability augmentation of mixtures under irradiation is caused by the decrease in the concentration of radiation defects in the anion sublattice of barium titanate.
