HEXAMINE COMBUSTION SYNTHESIS OF LANTHANUM NICKELATE

This work presents the synthesis of LaNiO3perovskite by simple combustion synthesis using hexamine as the fuel. The samples were characterized by X-ray Diffraction (XRD) and FT-IR. Inorder to identify the thermal decomposition and dissociation reactions, differential thermal analysis (DTA) and thermogravimetric analysis (TGA) were performed. The elemental analysis of the powder was assessed using Energy Dispersive X-ray analysis (EDS) technique. The morphological features of the powders were examined by Scanning Electron Microscopy (FESEM).
