In the present investigation, cobalt substituted zinc ferri-chromites were prepared by sol-gel auto-combustion method. The completion of solid state reaction and the formation of spinel phase were identified using X-ray diffraction technique. All the compounds exhibit cubic spinel symmetry and lattice constant shows an irregular trend with substitution of Co. Infra-red spectral studies shows an two strong bands, one around 600 cm(-1) which is attributed to the intrinsic vibrations of tetrahedral complexes and the other at 400 cm(-1) is due to octahedral one. The morphology and size of the particles was found out by scanning electron microscopy while the elemental compositions by elemental dispersive X-ray spectroscopy. The various compounds of the present system Zn1-xCoxFeCrO4 were also investigated for their thermal and electronic studies.</p>1 aHankare, P., P.1 aVader, V., T.1 aSankpal, U., B.1 aPatil, R., P.1 aJadhav, A., V.1 aMulla, Imtiaz, S.  uhttps://library.ncl.res.in/content/synthesis-and-characterization-cobalt-substituted-zinc-ferri-chromites-prepared-sol-gel-0
