Dependence of kinetics of borate glasses dissolution on the conditions of their γ-irradiation

Differences in the effects of reagents for the case when glass samples: a) are irradiated at the temperature of gamma-source channel 343 K; b) are remelted in gamma-field of 60Co (thermoradiation founding) are detected and compared. The comparison of the results, obtained in the present work for glass 14K2Ox86B2O3 with CuO additions according to the effect of fixed doses of γ-irradiation and thermoradiation leads to the indirect conclusion that irradiation at the temperature of γ-source channel promotes the consolidation of Cu2+ ion segregation range dimensions, whereas thermoradiation effect decreases them. As a result chemical equilibrium shift is possible during valence transformations of copper ions to the side of lower valence Cu2+ → Cu1+. The first conclusion agrees with electron microscopic studies, the other one is confirmed by the data of optical and ESR spectroscopy
