The calculations of thermophysical properties of low-temperature indium plasma

Abstract

A model for calculation of thermophysical properties (pressure, internal energy, electrical and thermal conductivities, and thermal power) of low-temperature indium plasma is developed at the temperatures 8–100 kK and densities less than 9 g/cm3. It is constructed on the basis of a chemical approach and a relaxation time approximation. The former allows us to obtain the chemical (ionic) composition of indium plasma together with the other thermodynamical values. There have not been any published data concerning these properties in this area for indium plasma up until now, excluding for the semi-empirical models. The area of applicability of the present model has also been estimated. The fitting analytical relations for calculated values, which can be used in practical applications, are constructed.
