Abstract
The relation between the activation energy and the preexponential factor in the Arrhenius equation that describes the viscosity and electrical conductivity of oxide (slag) melts is systematically analyzed over wide composition and temperature ranges for the first time. When deriving this relation, we do not use any model concepts and assumptions concerning the structure of slag melts or the character of electric charge transfer in them. The fundamental applicability of the Meyer-Neldel rule for this relation is shown and grounded. The application of this algorithm in practice can give information on the structure of experimental data, nonobvious correlations, and possible relations of a higher order and can quantitatively predict the behavior of parameters, including the range outside experimentally determined data.
