| Abstract: | Diffusion coefficients of various polyvalent ions (Sn2+, As3+, As5+, Sb3+, Sb5+, Cr3+, Ti4+, V4+, V5+ and Fe3+) were measured in melts with the basic compositions of 10CaO·10 BaO·10Al2O3·70SiO2 and 10CaO·10BaO·15Al2O3·65SiO2 by means of square-wave voltammetry. At temperatures in the range of 1300-1600 °C, linear correlations between logD and 1/T were observed. At 1400 °C, the diffusion coefficients obtained are compared with those obtained from other glass melt compositions. |
