Cobalt doped Titanium Dioxide (TiO₂) were synthesized by a standard solid-state reaction method. The formation of the single-phase compound and its structural parameters were investigated by X-Ray diffraction (XRD) followed by refinement using Xpowder and Scanning Electron Microscope (SEM) techniques. A better agreement between the observed and calculated XRD patterns was obtained by performing the refinement with a structural model using the space group I 41/amd. SEM image shows a spherical uniform shape of the particles.
