Thermodynamic Assessment of Liquid Mn–Fe–Si–C–Ca–P System by Unified Interaction Parameter Model

“…Si-C, 34,35,[45][46][47]56,[61][62][63][64] Mn-Fe-Si-C, 35,56,57,[63][64][65] Mn-i-Ca (i = Fe, Si or C) 46,66,67) and Mn-P. [68][69][70] However, reliable thermodynamic data are still very short to calculate the activities of different components in manganese ferroalloys at present. Since experimental measurements are both time-consuming and difficult at high temperatures, it is not possible to provide thermodynamic data for slag compositions in the many metallurgical processes; hence the need for a reliable model to estimate is urgent.…”

“…[20][21][22][23][24][25][26] In order to get a full understanding about the thermodynamics of the reducing de-P process, it is of great importance to know the activities of different components involved in the manganese ferroalloys, such as Ca, P, Si, Mn and C. Efforts have been devoted to describe the thermodynamic properties of Mn-based melts. A large amount of experimental works has been done for the systems Mn-Fe, [27][28][29][30][31][32][33] Mn-Si, [34][35][36][37][38][39][40][41][42] Mn-C, 35,36,[43][44][45][46][47][48][49][50][51] Mn-Fe-Si, 52,53) Mn-Fe-C, [45][46][47]49,[54][55][56][57][58][59][60] Mn-…”
