Abstract:To investigate the diffusion behavior of Tl ions, glass was immersed in TlNO 3 KNO 3 molten salt at 753 K for various lengths of time. The Tl ions embedded in the glass were then reduced to metallic Tl nano-particles by hydrogen at 803 K for 1 h. The depth of the ion exchange layer down to about 140 µm in the glass was found to be proportional to a square root of the length of immersion time. It was suggested that the ion exchange process is controlled by the diffusion of Tl ions from the surface to the inside… Show more
“…Ueda et al investigated molten salt ion exchange of Tl ions into glass at 753 K during lengths of time. 21 They stated that the spread of Ti ions from the outer to inner layers of glass limits the process of the ion exchange. 21 Therefore, this colour variance is related to the loading amount of copper ions into the clays' structure.…”
