Densities of Sb–Bi melts

Temperature-dependent densities of Sb, Bi and Sb–Bi melts have been investigated systematically using an improved Archimedean method. It was demonstrated that the density of Sb melts decreased linearly with increasing temperature, whereas the density of Bi melts hardly changed monotonously during the heating process. Furthermore, there were anomalous regions at the range of 20–50 K above the melting point of Sb–Bi melts, and the liquid phase regions can therefore be divided into two parts: structural compacting and structural loosing segments.
