Abstract
Diffusion of Tl+ ions was determined in a multicomponent glass by means of an ion‐exchange technique. Diffusion coefficients of Tl+ ions of 9.86×10—7 to 4.34×10−10 cm2/sec were calculated for glass which was immersed at 450 °C for 24 h in TlNO3‐KNO3 molten salts with the composition Tl/(Tl+K) =0.1 to 0.5.
