Abstract
The self-diffusion coefficients of the cation (D+) and of the anion (D-) have been measured in molten silver iodide be tween 580 °C and 620 °C with the porous-frit technique. At 610 °C it is found that D+ = D-=5A × 10-5 cm2 s-1. At the melting point (556 °C) D+ melt (4.4 × 10-5 cm2 s-1) is very close to D+ solid (4.3 × 10-5 cm2 s-1) . The Klemm friction coefficients do not indicate the existence of complex entities. D+ and D- calculated according to the Nernst-Einstein equation agree with observed data within 20%.Keywords
