Abstract
Solid solutions in the system CuxInyCr2Se4 were obtained from the elem ents by the ceramic method at 800 degrees C. They were examined by X-r ay diffraction. The changes in the values of the lattice constants (Cu Cr2Se4, a=10.335 Angstrom; Cu0.2In0.8Cr2Se4, a=10.716 Angstrom) in sam ples with the compositions CuxIn0.33(2-x)Cr2Se4, CuxIn0.67(1-x)Cr2Se4 and CuxIn(1-x)Cr2Se4 respectively are discussed as well as the influen ce of the indium amount on the variation in the copper valence in CuCr 2Se4.
