Phase equilibria in the Gd–Bi–Sb ternary system at room temperature

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].…”

“…Recently, the phase diagram of the Gd-Bi-Sb ternary system had been determined at room temperature using X-ray powder diffraction and differential scanning calorimetry analysis by Jian et al [15]. There were composed of six single-phase regions, six two-phase regions and one three-phase region.…”

“…The compounds, Gd 5 Sb 3 , Gd 4 Sb 3 , Gd 16 Sb 39 , α-GdSb and β-GdSb in the Gd-Sb system were assessed in the present work. The experimental results of Jian et al [15] were given more weight during the process of optimization. The thermodynamic parameters for the Gd-Bi-Sb system were optimized on the basis of the experimental information available in the experimental data [15].…”

“…The thermodynamic parameters for the Gd-Bi-Sb system were optimized on the basis of the experimental information available in the experimental data [15]. The experimental results of Jian et al [15] were given more weight during the process of optimization. The thermodynamic parameters of liquid, bcc, rhomb and hcp in the Gd-BiSb system, are obtained by a combination of the corresponding Gibbs energy functions from the assessments of the binary systems using Muggianu interpolation of binary excess terms [20].…”
