In this paper sol-gel method was used to synthesize Cu1-xZnxFe2O4 samples. Nitrates of magnesium, zinc and iron with purity of 97.00% were mixed with 80 ml of distilled water. To homogenize the resulting solution a constant stirring was used. The pH of the mixture was adjusted to 7 by ammonia while heating on a hot plate at 60° for 30 min. This procedure was followed by raising the temperature to 80° and continuous heating for 3 h to form the gel, which was dried at 120° to a complete burn out resulting in formation of fluffy structure. The fluffy structure was ground for 3 min using electric grinder to form fine ferrite powder. Powder was calcined at 500° for 4 h and sintered at 1000, 1100 and 1200°. The influence of sintering temperature on physical and magnetic properties of samples was studied by measurement of the absorbance of microwaves and the attenuation coefficient. The structure and morphology of prepared samples have been determined using XRD analysis and SEM. |
