A crystallization conditions study of the Ti-doped barium hexaferrite powders synthesized with the glass crystallization technique for microwave applications. - In: Materials science and engineering technology, ISSN 1521-4052, Bd. 42 (2011), 8, S. 731-736
For microwave applications Titanium doped M-type hexagonal ferrites have been synthesized by means of Glass Crystallization Technique varying the crystallization parameters and the melt doping concentrations. The chosen melt dopings were x = 5.4 and 7.2 mole-% TiO2 with the following basic composition (mole-%): 40 BaO + 33 B2O3 + (27-x) Fe2O3 + x TiO2. We have studied the dependencies between the magnetic properties, the valence of the iron ions in the glasses and the powders, the formation of new dielectric phases and the microwave absorption. - After the Ti4+ ions substitutions, the magnetocrystalline anisotropy changed, this effect was observed in the static magnetic properties (JHC and MS) measured using a Vibration Sample Magnetometer. Furthermore the Ti4+ ions preferably occupy mainly the 2a as well as slightly the 2b sites in the lattice of the barium hexaferrite, which are studied using Mössbauer spectroscopy. Besides, the X-ray diffraction studies proved that the formation of the ferrimagnetic (BaFe12-xTixO12) and dielectric (BaTi6O13) phases are dependent on the crystallization parameters. - The controlled influencing of lattice sites occupation and of the Fe2+ content in the ferrimagnetic phase as well as the controlled formation of the dielectric phase rate during the annealing are possibilities to optimize the microwave absorption of Ti-doped barium hexaferrite powders synthesized by Glass Crystallization Technique. - Keywords: barium hexaferrite, microwave absorber, Mössbauer spectroscopy, titanium substitution, X-ray diffraction
