Study of the preparation and characterization of copper ferrite including ferritization of copper scraps

ABSTRACT

Samples of copper ferrite, CuFe2O4, were prepared using both dry and wet processes, either from powders of iron oxide or from interaction of copper and iron sulfates, or co-precipitation of copper and iron hydroxides from homogeneous sulphate solutions at different pH values. Also, a sample of copper ferrite was prepared in optimum conditions from copper scraps. The effects of temperature and time of ferritization were studied. The prepared samples were investigated by X-ray diffraction analysis, differential thermal analysis, DTA, and scanning electron microscopy, SEM. Optimum conditions were found to depend on the input materials, the pH values, time and temperature
