Thermodynamic assessment of the Fe-Te system. Part II: Thermodynamic modeling

“…This must be carefully regarded when optimizing the system. Mikler et al [11] noted an anomalous increase in heat capacity in their measurement on the phase; while they cannot explain it, they suggest that perhaps pure tellurium was precipitated during the measurement. This is possible since the solubility limits were not well known at the time; with an updated suggested phase boundary from the experimental results obtained in Part I: Experimental study, an explanation will be suggested in order to decide whether or not this increase should be modeled.…”

“…The , and parameters (in Eq. 6) of the -and -end-members were fitted to the available data [10,11]. The parameters for the phase were then fitted to enthalpy of formation by Shukla et al [8] and theend-member formation energy evaluated in this work.…”

“…Enthalpy measurements have been performed in the and + regions [7][8][9]. Heat capacities have been measured on the and phases [10][11][12]. No enthalpy or heat capacity data are available for the and phases.…”

Estimation of liquid/liquid interfacial tensions of metallic mixtures using two-scale-factor universality

“…Experimental heat capacity data are available in the literature for the system bismuth/gallium. 8 Results of measurements of the liquidlliquid coexistence curve suggest that this system belongs to the same universality class as binary nonmetallic liquid mixtures. 9 In the vicinity of the critical point the liquidlliquid coexistence curve is represented by a function of the form ICPc-cpl =K(Tc-T)/3 with {3~0.33, where cP is the volume fraction and K a constant.…”

“…The reported CAm data 8 The theoretical value of RtA=0.27 adopted comes from a field theoretical expansion in 3 dimensions RtA= (0.2700±0.OOO7) 10 and a series analysis and Monte C!r1o result RJf=~?2659±0.OO07).1O _~ogether with Ao =2.4 J mol K ,M=111.5 g mol ,and Pc(300 K);:::;8 g cm-3 for x(Bi) =0.3 [and Aci =5 J mol-1 K-t, The value of sci can be considered only as a rough estimate owing to the uncertainty of the experimental data. It is of the same order of magnitude as that of the other two metallic systems considered in this communication.…”
