Identification of solid solutions of coprecipitated Ni-Co oxalates using XRD, TG and SEM techniques

Homogeneous solid-solution oxalates of Ni 2+ and Co 2+ ions were synthesized by coprecipitation from nitrate solutions using a double-inlet technique. The identification of the solid solutions used X-ray powder diffraction (XRD), thermogravimetry (TG) and scanning electron microscopy (SEM) technique...

Description
Summary:Homogeneous solid-solution oxalates of Ni 2+ and Co 2+ ions were synthesized by coprecipitation from nitrate solutions using a double-inlet technique. The identification of the solid solutions used X-ray powder diffraction (XRD), thermogravimetry (TG) and scanning electron microscopy (SEM) techniques. The experimental results showed that the coprecipitated powders have characteristics that are different from those of the mechanical mixtures with the same stoichiometry.
