Abstract
Phase equilibria in the binary system NaCl-RaCl2 were predicted based on the binary systems NaCl–MCl2 (M = Ca, Sr, Ba). All the considered systems are of the eutectic type. Experimental data were processed, and functional dependences Te/Z = f(Z) and Te/r = f(r) were obtained, where Te is the melting point of the eutectic in the binary systems NaCl–CaCl2, NaCl–SrCl2, and NaCl–BaCl2; Z is the atomic number of Ca, Sr, or Ba; and r is its ionic radius. By further calculations using these functions, the melting point of the eutectic in the NaCl–RaCl2 system was found. Using the Schröder–Le Châtelier equation, the composition of the binary eutectic in the predicted system and the molar enthalpy of melting of RaCl2 were calculated, and branches of the liquidus of the system were constructed.
