Abstract
A detailed investigation on the effect of preparation method on the structural, thermal and morphology Cu-Co ferrite nanoparticles prepared by solution combustion method. The resulting ferrites were calcined at 450℃ and 750℃. Sharper X-ray diffraction (XRD) peaks were observed for the samples calcined at 750℃, indicating greater crystallinity of the samples calcined at higher temperature. Average crystallite sizes fell in the ranges of 30.4–42.1 nm for the samples calcined at 450℃ and 750℃, respectively. Agglomeration of particles was observed in the scanning electron microscopy (SEM) images. Cumulative acidity decreased for the samples calcined at higher temperature. The results underline the effect of preparation conditions on the morphology, crystallite size, and magnetic properties of nano ferrites. The thermal properties such as onset of decomposition and glass transition temperatures were determined by Thermo Gravimetric Analysis (TGA/DSC). The TGA data shows that nanoferrites have significantly enhanced thermal stability. Thermal studies on as prepared samples have been undertaken over a wide range of decomposition at room temperature to up to 1000⁰C.
