The isothermal section of the Lu-Ge-In phase diagram at 870 K over the whole concentration range has been constructed using X-ray phase analysis. Only LuGe1-xInx (x = 0.035) compound (CrB-structure type, space group Cmcm, a = 4.1582(1), b = 10.4616(4), c = 3.8664(1) A) is formed in the ternary system. The Lu5Ge3 compound dissolves up to 10 at. % of indium along the isoconcentration of lutetium 62.5 at. %.

The interactions between components in Zr-Cu-In ternary system at 870 K have been studied by X-ray and microstructure analyses. One earlier known (ZrCu2In with MnCu2Al-type) and four inknown ternary compounds have been found. Crystal structure of all new compounds are determined: ZrCu5-xInx (x=0.3-1.3)-AuBe5 type of structure (space group F43m, a=6.955-7.042(2)A; ZrCuxIn3-x(x=0.35-0.80)-AuCu3 type of structure (space group Pm3m), a=4.3281-4.3079(1)A; Zr2Cu2In-Mo2FeB2type of structure (space group P4/mbm),a=7.194(2)A, c=3.410(4)A; Zr5CuIn3-Hf5CuSn3 structure type (space group P6(3)/mcm, a=8.671(2)A, c=5.917(1)A).

The interactions between the components in the ternary Zr-Ag-In system were studied. An isothermal section at 870 K was established by X-ray analysis. Two unknown ternary compounds have been found: ZrAg-0.4In-2.6-AuCu3 structure type (space group Pm3m, a=4.3644(4) A and Zr5AgIn3-Hf5CuSn3 structure type (space group P6-3/mcm, a=8.735(3) A, c=5.948(2) A). Their crystal structures were determined by powder X-ray analysis.
