Abstract
The densities of Sb and Bi melts were investigated by an improved Archimedean method. The results show that the density of the Sb melt decreases linearly with increasing temperature, but the density of the Bi melt firstly increases and then decreases as the temperature increases. There is a maximum density value of 10.002 g/cm3 at 310°C, about 39°C above the melting point. The temperature dependence of the Sb melt is well fitted with the expression ρ=6.8590−5.8105×10−4 T, and that of the Bi melt is fitted with ρ=10.3312−1.18×10−3 T. The results were discussed from a microstructure viewpoint.
