Abstract

When the melting point is paproached from higher temperature, certain melts show an increase of viscosity considerably greater than the usual exponential temperature dependence (for example, monoatomic liquid metals). There is model in which this feature is attributed to cluster formation.
In this paper we have derived an expression for the viscosity of liquids with large temperature dependence. This is a generalization of already obtained theory, based on the Einstein model and monentum transfer taking place at every extreme displacement (by S.Takeuchi and T.Iida).
Cluster shapes and the temperature dependence of clutering can be estimated semi-quantitatively by this expression.
