AbstractA thermodynamic model for calculating the mass action concentrations of structural units in Fe-P binary melts based on the atom-molecule coexistence theory, i.e., AMCT-N-i model, has been developed and verified through comparing with the reported activities of both P and Fe in Fe-P binary melts with mole fraction x(P) of P <0.33 in a temperature from 1406 K to 1973 K. The calculated mass action concentration N-P of P or N-Fe of Fe has a very good 1:1 corresponding relationship with the reported activity a(R,P) of P or a(R,Fe) of Fe relative to pure liquid P(l) or Fe(l) as standard state, and can be applied to substitute the measured activity a(R,P) of P or a(R,Fe) of Fe in Fe-P binary melts. The Raoultian activity coefficient gamma(0)(P) of P and gamma(0)(Fe) of Fe in the infinitely dilute solution of Fe-P binary melts in a temperature from 1406 K to 1973 K have been determined from the calculated mass action concentrations N-i of structural units in Fe-P binary melts. The activity a(R,i), a(%,i), and a(H,i) of P or Fe relative to three standard states have been obtained. The values of the first-order activity interaction coefficient epsilon(i)(i) or e(i)(i) or h(i)(i) of P and Fe related with activity coefficients gamma(i) or f(%i) or f(H,i) of P and Fe in Fe-P binary melts are also determined.; A thermodynamic model for calculating the mass action concentrations of structural units in Fe-P binary melts based on the atom-molecule coexistence theory, i.e., AMCT-N-i model, has been developed and verified through comparing with the reported activities of both P and Fe in Fe-P binary melts with mole fraction x(P) of P <0.33 in a temperature from 1406 K to 1973 K.
