Effect of thermal parameters and pH on obtaining copper ferrite via EDTA-Citrate complexation method

The synthesis of ceramic materials such as ferrite has been widely studied in recent years, due to their properties that make these have excellent applications technology, well photocatalytic processes and catalysts. To obtain the copper phase EDTA-Citrate complexation method was used, varying pH (5, 7 9), temperature (600, 800 1000 °C) calcination time (2, 12 h). Composition, morphology structural analyzes were performed by X-ray fluorescence spectroscopy, dispersive energy, scanning electron microscopy diffraction, respectively. Crystalline (CuFe2O4) with tetragonal structure secondary Fe2O3 CuO verified XRD analysis. Regarding chemical composition analyzes, percentage deviations samples theoretical value for iron calculated. It obtained minimum values 0.16 - 0.08% (atomic%, EDS) 16 8% XRF) relation iron, respectively, sample under 9, calcined at 600 °C h. variation condition via directly influenced ferrite, presenting agglomerated particles, pore formation, irregular spheres, even powder sintering.
