The ternary system Hf–Ga–Sb at 600ºC

Abstract: The isothermal section at 600ºC of the phase diagram of the ternary system Hf-Ga-Sb was constructed in the whole concentration range, using X-ray powder diffraction. Limited solid solutions based on the binary compounds HfGa (17 at.% Sb), Hf 5 Ga 3 (11 at.% Sb), and Hf 5 Sb 3 (3 at.% Ga) were observed. Four ternary compounds form at 600ºC: Hf 2 GaSb 3 (structure type Zr 2 CuSb 3 , Pearson symbol tP6, space group P-4m2, a = 3.89841(8), c = 8.62650(19) Å), HfGa 0.1 Sb 0.9 (FeSi, cP8, P2 1 3, a = 5.5752(3) Å), Hf… Show more

“…Ternary phases with Hf 5 CuSn 3 -type structures have also been reported for related systems with Zr and Hf. Zr 5 AlGe 3 [23] and Hf 5 GaSb 3 [24] are ternary compounds, whereas Hf 5 GaSn 3 is the limiting composition of the inclusion-type solid solution Hf 5 Ga x Sn 3 (x = 0-1) [25,26]. For two phases, Zr 5 AlSb 3 [27] and Zr 5 GaSn 3 [3] the way of formation is not known.…”

“…The existence of the ternary compound Sm 5 Ga 0.76 Sn 2.24 with Nb 5 SiSn 2 -type structure along the line Sm 5 Ga 3 -Sm 5 Sn 3 makes the system Sm-Ga-Sn similar to related systems containing heavy d-metals instead of rare-earth metals. Isotypic phases were recently found in the systems {Zr,Hf}-Ga-{Sn,Sb} [33][34][35] and Ta-Ga-Sn [36]. The compositions of the Nb 5 SiSn 2 -type ternary compounds usually contain higher contents of the p-element that is heavier and has larger atom size.…”
