تأثیر pH بر خواص ساختاری و مغناطیسی نانوذرات PbFe12O19 ساخته شده به روش سل- ژل

In this research, lead hexaferrites nanoparticles (PbFe12O19) were prepared by sol-gel method. The effect of pH on the structural and magnetic properties of PbFe12O19 was studied. The attempt in this paper was to depict the effect of change in sol-gel pH on the size and morphology of the samples as well as their structural and magnetic properties. Therefore, samples with pH = 1.8, 3, 5, 6, 7, and 8 were prepared. Then, the dry gels of the samples were heated in the optimum annealing temperature and time of 800 oC and 3 h, respectively. In order to study the structural, morphological and magnetic properties of the samples prepared in various pHs X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Vibration Sample Magnetometer (VSM), and LCR meter were applied, respectively
