- Abstract
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 xP of P <0.33 in a temperature from 1406 K to 1973 K. The calculated mass action concentration NP of P or NFe of Fe has a very good 1:1 corresponding relationship with the reported activity aR,P of P or aR,Fe of Fe relative to pure liquid P(l) or Fe(l) as standard state, and can be applied to substitute the measured activity aR,P of P or aR,Fe of Fe in Fe-P binary melts. The Raoultian activity coefficient
