THE RCuIn1–xGax (R = La, Ce) SYSTEMS AT 870 K

The presented work is devoted to the study of LaCuIn1-xGax and CeCuIn1-xGax systems for the purpose of solubility of the fourth component in equiatomic compounds and structural characteristics of solid solutions. The samples for the investigation were synthesized by arc-melting of metals (purities better then 0.998) with subsequent annealing at 870 K for a month. The phase compositions of the alloys were characterized by means of X-ray powder diffraction (DRON-2.0M, FeKα-radiation, HZG-4a, CuKα-radiation) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM Tescan Vega 3 LMU).
According to the results of experimental studies in the LaCuIn1-xGax system at 870 K, the solubility of Gallium in the LaCuIn compound is 6.7 at. % and the composition of solid solution is LaCuIn1–0.8Ga0–0.2 (ZrNiAl-type structure; a = 0.75500–0.75234(8); c = 0.42800–0.42963(6) nm; V = 0.21128–0.21060(4) nm3). The 16.7 at. % of Indium dissolves in the LaCuGa compound, and solid solution described by formula: LaCuGa1.0–0.5In0–0.5 (KHg2-type structure; a = 0.45439(8)–0.46393(18); b = 0.74991(16)–0.76130(35); c = 0.75760(14)–0.76916(31) nm; V = 0.25815(3)–0.27166(6) nm3).
In the CeCuIn1-xGax system at 870 K we observed the formation two limited solid solutions with the structures of starting compounds: CeCuIn1.0–0.8Ga0–0.2 (ZrNiAl-type structure; a = 0.74915–0.74425(12); c = 0.42452–0.42794(9) nm; V = 0.20633–0.20528(6) nm3) and CeCuGa1.0–0.5In0–0.5 (KHg2-type structure; a = 0.45078(10)–0.45787(14); b = 0.74005(17)–0.74945(25); c = 0.75207(16)–0.76222(24) nm; V = 0.25089(9)–0.26155(6) nm3). In the both systems in equilibrium with the main phases there is a phase with a MnCu2Al-type structure in almost the entire concentration range.
Comparison of the studied systems with the previously studied systems RTIn1–xMx (R = La, Ce, Y, Gd, Tb; T = Ni, Cu; M = Al, Ga, Ge, Sb) indicates common trends of nature of the interaction between the components.

Keywords: gallium, indium, powder data, solid solution.
