An investigation of the Ir-Ga-As system

Electronic structure, phase stability, and vibrational properties of Ir-based intermetallic compound IrX (X=Al, Sc, and Ga)

“…The lattice constants and bulk modulus have been optimized by minimizing the total energy with regards to volume using the equation of state (EOS) by Murnaghan [37]. In Table 1, we summarize our calculated equilibrium lattice constants of IrX (X ¼Al, Sc, and Ga) compounds compared with the available experimental and theoretical data [13][14][15]17,25,28,38]. Our values of the lattice parameter agree well with the experiment.…”

The ternary systems Al–Ga–Pd and Ga–Sb–Pd. Search for new catalytic materials

“…The systems Ga-M-T have not been thoroughly investigated (Table 1, [4]). Of the 66 ternary systems Ga-M-T, isothermal sections of the phase diagrams (mainly partial; calculated or experimental) have been constructed only for 10: Ga-As-Rh [5][6][7], Ga-{Si,Ge,As,Sb}-Pd [5,[8][9][10][11], Ga-As-{Os,Ir} [5,12], and Ga-{Ge,As,Sb}-Pt [5,[13][14][15][16][17][18] (Table 2). 14 ternary compounds, representing 11 structure types, have been reported in the following systems: Ga-{Ge,As}-Rh [10,19], Ga-{Si,Ge,As,Sb,Bi}-Pd [3,[8][9][10]20,21], Ga-B-{Ir,Pt} [22,23], and Ga-Ge-Pt [13] (Table 3).…”
