There is a unit proposed for investigations in the high-temperature metallic liquid alloys, using image photometry of a “large melt drop” resting on the horizontal backplate. The unit is designed to determine the density d and surface tension σ of a sample of the mass given, placed into a horizontal electric furnace. Using a volumenometer enables measuring the geometric parameters of the drop. Various ways of expanding the range of operational functions are presented, in particular, extending the temperature range Δto and improving the unit efficiency as well as decreasing the artifacts’ impact. Updating the unit enables the studies (including the comparison studies) of both luminous and nonluminous samples to be conducted combining various ways of illuminating both the melt drop’s contours and surface. The ways of reducing the influence of vibrations and refining the backplate’s horizontal position as well as the possible measures for partial cleaning the films from the drop surface of the multicomponent melt are proposed. The use of the unit updated on the basis of approaches developed and patented by the authors enables reducing the time to be spent on measurements, expanding the range of the unit’s operational functions, decreasing the artifacts’ impact and improving the validity of the results obtained.

Quadrupolar Relaxation

A theory of the quadrupolar relaxation rate,RQ , for ideal liquid binary metallic mixtures ispresented. The theory predicts cancellation after a few tenths of a picosecond of the two andthree particle correlation terms in the fluctuation of the electric field gradient (EFG) for puremetals, and prevailing of the three particle term for binary mixtures. This is due to the highsymmetry in the arrangement of the atoms around a probe nucleus. The prevailing of the threeparticle term in binary systems leads to a longer correlation time (a few picoseconds) of thefluctuating EFG and explains the experimentally observed higher values of RQ and theirquadratic concentration dependence. The validity of the theory has been confirmed by experimentaldata. Deviations for some real systems are discussed.
