提出了熔盐溶液的溶解能参数的概念,熔盐系A_nB_m-A_(n′)C_(m′)(A离子之价数为Z)的溶解能参数为: 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) 熔盐系A_nB_m-C_(n′)D_(m′)(C离子之价数为Z′)的溶解能参数为: 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~2(n+m)/m(r_A+r_B)-n′Z′Z(n′+m′)/m′(r_C+r_D)。溶解能参数是熔盐静电混合能的近似函数,当f(r)为正值时,溶液呈现负偏差,当f(r)为负值时,溶液呈现正偏差,f(r)可作为估计熔盐溶液的热力学性质和二元熔盐相图的近似方法。
The solubility parameter of molten salt solution A_nB_m-A_ (n ’) C_ (m’) (the price of A ion is Z) is proposed as follows: f (r) = Z ~ 2nn (R_A + r_B) + Z ~ 2n ’~ 2 / m’ (r_A + r_C) -2Z ~ 2nn ’/ (2r_A + r_B + r_C) (n’ / nm ’+ 1 / m) The energy parameter of A_nB_m-C_ (n ’) D_ (m’) (the price of C ion is Z ’) is: 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 ~ 2 (n + m) / m (r_A + r_B) - n’Z’Z (n The solubility parameter is an approximation function of electrostatic mixture energy of molten salt. When f (r) is a positive value, the solution shows a negative deviation. When f (r) is negative , The solution shows a positive deviation, f (r) can be used as an approximation to estimate the thermodynamic properties of the molten salt solution and the binary molten salt phase diagram.
