Abstract
Abstract. The polycrystalline compounds in the ZnCr2-xNdxSe4 system were prepared by the ceramic method in closed silica tubes using ZnSe, Nd2Se3, and Cr2Se3 as starting materials. The chemical composition and structural data has been determined by X-ray diffraction. The observed symmetry is cubic, space group . For ZnCr1.95Nd0.05Se4 compounds, a pure spinel phase forms for stoichiometric and smaller amounts of ZnSe. For both compounds of ZnCr1.90Nd0.10Se4, near spinel phase, a foreign ZnSe phase exists. It may indicate that 10% doping is close to the solubility limit of Nd in ZnCr2Se4.
