Gd–Co–Ge system at 870/1070 K

X-ray phase analysis and microprobe analysis were employed in constructing the isothermal section of the Gd–Co–Ge system at 870/1070 K. The isothermal section contains the known YCo6Ge6-type Gd0.8Co6Ge6, CeGa2Al2-type GdCo2Ge2, Lu2Co3Si5-type Gd2Co3Ge5, Y3Co4Ge13-type Gd3Co4Ge13, CeNiSi2-type GdCo0.44Ge2, TiNiSi-type GdCoGe, Hf3Ni2Si3-type Gd3Co2Ge3, Sc2CoSi2-type Gd2CoGe2 and La3NiGe2-type Gd3CoGe2 ternary compounds. rnary solid solution based on the binary compounds of the Gd–Co system and AlB2-type Gd2Ge3 were detected the isothermal section at 870/1070 K. The other binary compounds of the Gd–Co–Ge system do not show any visible solubility.
