Electrical resistivity of liquid Sb-Te solutions

The specific resistivity of liquid antimony-tellurium alloys was determined by the DC four probe method. The cell with the capillary was used to measure potential drops in the temperature range 820-1150 K for pure antimony and six alloy compositions up to X-Te=0.6. Using experimental results obtained in the present study the resistivity change with the alloy composition at constant temperature was derived. It was demonstrated that depending on local ordering in the liquid state there is a interdependence between oxygen activity coefficient, diffusivity and the alloy conductivity measured in Sb-Te binary system.
