摘要

On the basis of concepts presented on the structure of glass considered favorable for complete ion exchange of monovalent cations in the 'glass-salt melt' system, a composition of alkaline multicomponent phosphate glass has been proposed, which is effective in speeding the process of interdiffusion of alkaline cations. The glass of composition, Me2O-RxOy-P2O5 where Me2O = Na2O + K2O and RxOy = B2O3 + ZrO2 + Nb2O3 + Al2O3 + SiO2 + Nd2O3 (formula unit) has been chosen as the initial one for ion exchange. During the ion exchange, gradient diffusion layers up to 1.7 mm thick hale been obtained in 8 h from a molten mixture of Li2SO4 and Li2MoO4, at temperatures above the glass transition temperature over the flat surface of a sample: the increase of the refractive index in the layer was equal to 0.027 +/- 0.002.
