“…Many researchers9–11, 13, 15, 21–23, 26, 27, 30, 32, 33, 36–38 had determined the Raoultian activity coefficient $\gamma _{{\rm Si}}^{0} $ of Si in the infinitely dilute solution of Fe–Si binary melts with various experimental methods since the 1950s, however, the reported9–11, 13, 15, 21–23, 26, 27, 30, 32, 33, 36–38 values of the Raoultian activity coefficient $\gamma _{{\rm Si}}^{0} $ of Si in the infinitely dilute solution of Fe–Si binary melts at temperature of 1873 K shows a large fluctuation in a range of 7.00 × 10 −4 –1.74 × 10 −2 from different researchers as summarized by Fujisawa et al37…”

“…The iron‐rich ferrosilicon alloy is one of the important alloys as deoxidizing and alloying agents for molten steel during steel refining processes because Si is one indispensable alloying element in the high‐performance steels, such as transformation induced plasticity (TRIP) steel, etc., as well as in the advanced magnetic materials 1. The thermodynamic properties of Fe–Si binary melts, especially the activity of Si, have attracted tremendous focus in the past several decades since the 1940s 2–49. Turkdogan et al23 and Zaitsev et al43 reviewed the literature on the activity of Si in Fe–Si binary melts prior to 1963 and 2003, respectively.…”

“…The reaction abilities mainly represented as activity a i of element i in FeSi binary melts have attracted tremendous focus in the past several decades since the 1940s . The main experimental methods for determining activity a Si of Si in FeSi binary melts can be summarized as measuring distribution ratio of Si between FeSi and AgSi binary melts through metal–metal equilibrium approach; measuring Si content in FeSi binary melts via gas–metal equilibrium method; measuring electromotive forces (EMF) by galvanic cells of Si sensor in FeSi binary melts; measuring vapor pressure of FeSi binary melts at the elevated temperatures; (5) measuring standard equilibrium constant of FeSi binary melts equilibrated with SiO 2 ‐containing slags in H 2 H 2 O atmosphere through gas–slag–metal equilibrium method; (6) determining partial molar mixing enthalpy change of Si and Fe; and measuring ion current ratio of FeSi binary melts through Knudsen cell–mass spectrometer . It was summarized by Zaitsev et al that the metal–metal equilibrium method between FeSi and AgSi binary melts can be used to determine activity of silicon in FeSi binary melts with high Si content, but cannot be applied to accurately determine activity of Si in FeSi binary melts with low Si content; the EMF method can cause the measured activity of Si in FeSi binary melts higher because of the exchange reactions between the solid electrolyte of silicon sensor and the electrode surface at high temperature about 1873 K; the gas–metal equilibrium method can be employed to determine activity of Si in FeSi binary ...…”
