摘要

The polycrystalline Cd_(0.5)Ge_(0.5)Cr_2Se_4 and CdCr_(1.9)Ge_(0.075)Se_4 compounds were obtained using ceramic method. X-ray analysis was used to make phase and structure analysis. The Rietveld method was applied for structure refinement. Both compounds crystallized in cubic, normal spinel structure, Fd 3 m. Besides the main spinel phase, Cr_2Se_3 was observed.
