Abstract
Hall effect and electric-conductivity data for liquid tellurium are analyzed by means of the two-species model. Liquid tellurium is proposed to consist of two species, the normal form and another, metallic, form similar to one of the high-pressure phases of tellurium. The analysis yields a value for the interaction energy w which explains the irregularity in the high-pressure melting curve reported by Stishov, Tikhomirova, and Tonkov. Isoconcentration lines in the p-T plane are constructed for liquid tellurium and also for liquid cesium.
