Effect of milling medium on the structure and magnetic properties of mechanically alloyed barium ferrite
Abstract
<p>Mechanical alloying of the mixture of Fe<sub>2</sub>O<sub>3</sub> and BaCO<sub>3</sub> powders in water leads to partial decomposition of barium carbonate and probably formation of barium hydrate Ba(OH)<sub>2</sub>. Application of steel vials for the milling in water results in their faster abrasive wear which is accompanied by enrichment of the powders in iron, in the form of Fe<sub>3</sub>O<sub>4</sub> phase. Phase constitution of the materials studied after ferritization at 1000 °C/1h obtained by milling in water, consists of BaFe<sub>12</sub>O<sub>19</sub> matrix with BaFe<sub>2</sub>O<sub>4</sub> and Fe<sub>3</sub>O<sub>4</sub> precipitates, whereas the sample obtained by milling in air contains only BaFe<sub>12</sub>O<sub>19</sub> matrix with numerous Fe<sub>3</sub>O<sub>4</sub> precipitates. The change in the microstructure does not explain however the differences observed in the magnetic properties, especially in the shape of the hysteresis loops. After milling in water the demagnetisation is dominated by nucleation of reverse domain whereas for the specimen milled in air conditions of pinning to the coercivity mechanism is evidenced. © 2008 Advanced Study Center Co.
