Research of the Fe₂O₃ Powder Granulation Effect on BaFe₁₂O₁₉ Firing Temperature

Abstract:

In the paper is presented the study of the Fe₂O₃ powders granulation effect on the firing parameters for the BaCO₃+6Fe₂O₃ powder mixture. The Fe₂O₃ powders were milled in a ball mill in wet medium. The results indicated that the granulation of Fe₂O₃ powders decreased rapidly with the increase of milling time. The Fe₂O₃ milled powders were then mixed with unmilled barium carbonate powders in order to form barium hexaferrite. After mixing, the powders were analized by thermogravimetric point of view and then the obtained barium hexaferrite samples were investigated by XRD analysis. It was observed that the firing temperature of the hexaferrites decreases with 10 degrees when we introduce in the mixture Fe₂O₃ milled powders with a fine granulation.
