Abstract

The Zr−Ru−Ga system has been partially studied in the region of 0−50 at. % Ga in [1−3], which revealed the existence of two ternary compounds with the MgZn2-type structure (space group (SG) P63/mmc): ZrRuxGa2-x (0.60 < x < 0.96), a = 5.2475(5) − 5.2557(1), c = 8.3923(7) − 8.2854(1) Å [1] and Zr1-xGaxRu2 (x = 0.18), a = 5.1399(1), c = 8, 4888(2) Å [2], and solid solutions based on binary RuGa and ZrRu compounds with the CsCl-type structure (SG Pm3m) [3]. In this work the Zr−Ru−Ga system was investigated in the region of high Ga content (>50 at. %) at 870 K.
