Abstract
The effect of oxygen and silicon impurities on the structural and physicochemical properties of the nickel melts is studied in performing evaluations based on the density and surface tension parameters. The behavior of the impurity elements is considered in studying the liquid state of pure nickel and nickel containing 0.005–0.01% silicon and oxygen in the course of refining these melts, in which the compression effect and negative deviations from Raoult’s law are formed. The surface tension of the silicon-containing nickel melt is found to increase with the oxygen concentration. The absorption parameters of a solution abruptly decrease in accordance with the increase in interparticle interaction in the volume and the formation of a strong cluster.
