Abstract A new concept, the "energetic parameter of solution", is suggested for molten salt solutions. For the A_n B_m—A_n' C_m' system (valency of A ion is Z):f(r)=(Z~2nn')/(m(r_A+r_B))+(Z~2n'~2)/(m'(r_A+r_C))-(2Z~2nn')/(2r_A+r_B+r_C)(n'/nm'+1/m)n>n'. For A_nB_m—C_n'D_m' system (valency of C ion is Z'): f(r)=(n'Z'Z((n+nZ)/(n'Z')m'))/(m'(r_A+r_D))+nZZ'(m+nZ/Z')/(m(r_B+r_C))-(nZ~3(n+m))/(m(r_A+r_B))-(n'Z'Z(n'+m'))/(m'(r_C+r_D)). The "energetic parameter of solution" is an approximate function of electrostatic energy of mixing of molten salts. When f(r) is positive, the solution exhibits negative deviation; when f(r) is negative, the solution shows positive deviation. The function f(r) may be used as an approximate method to estimate the thermodynamic properties of molten salt solutions, as well as phase diagrams of binary salt systems.
