A series of CuGa 1‐x In x Te 2 bulk quaternary compounds (x=0.17, 0.33, 0.50, 0.67, 0.83) has been synthesized from the corresponding stoichiometric melts by a rapid cooling procedure. The same procedure was used to obtain the ternary bulk compounds CuGaTe 2 and CuInTe 2 with the aim to compare, according the Vegard law, the match between molar fraction of the indium (x) and the lattice parameters for the aforementioned quaternary compounds. The nature of the crystalline phases, the local structure homogeneity and stoichiometry of these compounds have been investigated by x‐ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The analysis revealed the presence of the chalcopyritic structure for all the samples.
