“…Few experimental studies concerning critical phenomena have been carried out for metallic alloys at elevated temperatures. This is also true for the Bi-Ga system, for which measurements on electrical conductivity [2], structure [3,4], ultrasound velocity [3,5,6] and specific heat capacity [7] have already been reported. Commonly the measurements are not extended close enough to the phase separation line, and the temperature resolution capability is too low, to obtain information about critical phenomena.…”

The shear viscosity of Bi-Ga melts in the entire concentration range was measured using an oscillating-cup viscometer. The viscosity data well above the temperature of phase separation can be represented by an empirical equation of the Arrhenius type. The activation energies of viscous flow are given. In the vicinity of the critical point the viscosity increases as the temperature decreases. This behaviour is analysed in terms of various models. The critical exponent y is found to be y = 0.032 ± 003.

“…These values do not agree with any theories, as shown in table 1. Mikler et al [17] showed the maximum of C p at 70 at% Ga for liquid Bi-Ga system. The depression of the sound velocity with the approach to TLPS was found for liquid Bi-Zn [18], Tl-Te [19], Tl-Se [20] and Sb-Se [21] systems.…”

The process of two-liquid phase separation (TLPS) was studied by the electrical resistivity, ρ, both on the ground and under microgravity obtained on board the sounding rocket. On cooling to the critical temperature, Tc, on the ground, increase of ρ and decrease of the temperature coefficient of ρ, dρ/dT were found in the homogeneous liquid phase of liquid Bi–Ga and Cd–Ga alloys. However, increase of ρ and decrease of dρ/dT were observed for the liquid Hg–Ga system. Both tendencies were explained successfully by the concentration fluctuation model. The rocket experiment for the ρ of liquid Bi–Ga alloys revealed that, under microgravity, the concentration fluctuation grows extensively and the nucleation for TLPS is suppressed.
