Thermodynamic properties and phase equilibria in the alloys of the La—Sn and La—Ni—Sn systems

Abstract

By the method of calorimeter and model of individual adsorption of electricity in the form of thermodynamic power-handling of La—S n, La—Ni—Sn systems at 1600—1800 K in the storage area 0 ≤ xSn ≤ 0,2 і by triem, we will exchange the changes in the order. It is installed, the minimum value of the insulation of the systems of the La—Sn system is 50,5 kJ / mol at xSn = 0,54, and the activity of the component is determined by the negative correlation of the individual values of the individual values. It is experimentally assigned to the model of Redlich—Kistera, which is used to b uild La—Ni—Sn rods, and to minimize the amount of accumulation on the sub-system of La—Sn.
