Influence of the Substitution of Iron by Aluminum and Titanium on the Structure and Properties of Barium Hexaferrite
Abstract
Ionic substitution is considered to be an effective approach to modify functional characteristics of hexagonal ferrites. To this aim, solid solutions with iso- and aliovalent substitution of iron by aluminum and titanium, respectively, are prepared by the solid-phase synthesis. The influence of the Al3+–Ti4+ substitution on the structure and properties of BaFe12–xAlxO19, BaFe12–yTiyO19 is studied. The prepared solid solutions are studied by scanning electron microscopy and X-ray microanalysis, powder XRD, vibration magnetometry, and differential scanning calorimetry. The crystal structure data confirm that the synthesized samples are characterized by the hexagonal phase, the P63/mmc space group. The samples are shown to consist of 1-10 µm flat hexagonal crystals. The influence of substitution on their magnetic properties is determined. The substitution of Fe3+ magnetic ions by Al3+ and Ti4+ ions decreased the Curie point of the solid solutions. Since magnetic characteristics can be tuned by introducing Al3+ and Ti4+, this effect can be used to control the optimization of magnetic characteristics in BaFe12–xAlxO19, BaFe12–yTiyO19 solutions to solve applied problems.
