Pressure-temperature diagram of liquid antimony

Abstract

Pressure-temperature phase diagram of Sb melt has been studied. Liquid antimony was found to have four regions separated from each other by the sharp jumps of volume and electrical conductivity. Four new triple points connected with the transformations in Sb melt were detected. Kinetics of the transitions is discussed. Comparison of p-T diagrams of liquid and solid Sb is presented. A general rule concerning the triple points at the p-T diagrams of the melts is determined.
