Thermodynamic assessment of the Gd–Sb system

Thermodynamic Description of the Gd-Sb and Gd-Bi-Sb Systems

“…The four intermediate compounds, Gd 5 Sb 3 , Gd 4 Sb 3 , GdSb 2 , and GdSb were reported in this system. Recently, the previously called "GdSb 2 '' phase was determined to be Gd 16 Sb 39 [14], which was confirmed in the Gd-Bi-Sb ternary system [15]. So the Gd-Sb phase diagram was revised by Borzone et al [14].…”

“…So the Gd-Sb phase diagram was revised by Borzone et al [14]. All of the information of the Gd-Sb system was compiled by Li et al [16]. The updated phase diagram was assessed by Li et al [16].…”

“…All of the information of the Gd-Sb system was compiled by Li et al [16]. The updated phase diagram was assessed by Li et al [16]. The thermodynamic parameters of the Gd-Sb system were well reproduced [16], but the parameters of Bcc(Gd) were difficult to reproduce the temperature of the Bcc(Gd).…”

“…The updated phase diagram was assessed by Li et al [16]. The thermodynamic parameters of the Gd-Sb system were well reproduced [16], but the parameters of Bcc(Gd) were difficult to reproduce the temperature of the Bcc(Gd). In the present work, to assess the Gd-Bi-Sb ternary system, the model of the five intermediate compounds, Gd 5 Sb 3 , Gd 4 Sb 3 , Gd 16 Sb 39 , α-GdSb (GdSb-low temperature as GdSb-LT) and β-GdSb(GdSbhigh temperature as GdSb-HT), was re-built to cosistent with other thermodynamic parameters of the relative compounds in the Gd-Bi system [6].…”

“…So the thermodynamic parameters of the five intermediate compounds were re-assessed in the present work. Figure 3 presented the calculated phase diagram of Gd-Sb system using the thermodynamic parameters of the five intermediate compounds calculated in this work and the thermodynamic parameters of the liquid assessed by Li et al [16].…”
