Abstract :
Ba12-2xCoxTixO19(x=0, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9) ferrite fine particles were prepared by the glass crystallization method in the BaCo3-B2O3-Fe2O3glass system. The crystallization process of glass flakes, the morphology, particles size and magnetic properties of the Co and Ti substituted Ba-ferrite platelet particles have been investigated by differential thermal analysis, X-ray diffraction, TEM, magnetic measurement and Mössbauer spectroscopy.
