The effect of γ-ray-radiation on surface physicochemical processes on Al2O3

Year: 2025

Type: conference-paper

Abstract: The γ-adsorption effect was studied on γ-Al2O3 samples subjected to thermal vacuum treatment. As our experiments showed, the dependence of radiation adsorption centers on the preliminary annealing temperature has a non-monotonic nature. The maximum adsorption activity is observed at a temperature of 1073 K, and the minimum is in the temperature range of 700 - 900 K. The dose dependence of the amount of absorbed gas is also characterized by a maximum in the range of ∼ 0.01 Mg. With γ-radiation of Al2O3, an EPR signal appears, possessing electron and hole transport regimes, with two maxima: 1 - in the dose range of ∼ 0.01 MGy and 2 - in the dose range of 0.15 MGy.
