Abstract
The heat capacity for liquid Te-I mixtures has a marked concentration dependence. Large heat capacities are observed around the stoichiometric composition TeI 4 . Liquid Te 0.8 I 0.2 mixture shows a broad maximum in the temperature dependence of heat capacity. The magnetic susceptibilities for liquid Te 1- x I x mixtures with x ≥0.8 are nearly independent of temperature. In the intermediate concentration region, linear behaviour is observed in the plots of log χ p · T versus T -1 . Large excess heat capacities for I-rich mixtures can be attributed to the dissociation of polymeric complexes. For Te-rich mixtures, excess heat capacities are closely related to the change in the density of states near the Fermi level E F caused by the bonding rearrangement.
