| Abstract | Density measurements of molten solutions of thallium and tellurium have been made over the temperature range 220 to 650°C and the composition range 31 to 69 atomic per cent thallium. The Archimedian method was employed since it is readily adaptable to performing measurements over wide ranges of temperature and composition with a high degree of precision. The density-temperature curves are linear. These measurements yield the composition dependence of the density and coefficient of thermal expansion. The purpose of this work was to obtain information which would supplement known electrical data for liquid thalliumtellurium. In a particular composition range for which the liquid exhibits n-type behavior, conversion of the density to the number of atoms per unit volume provides a value which was needed to complete the calculation of the total electron concentration. Also, the average atomic volume demonstrates an unexpected dependence on composition. A discussion of this behavior is presented in terms of known electrical and thermodynamic data. |
