Abstract
In the paper is presented the study of the Fe2O3powders granulation effect on the firing parameters for the BaCO3+6Fe2O3powder mixture. The Fe2O3powders were milled in a ball mill in wet medium. The results indicated that the granulation of Fe2O3powders decreased rapidly with the increase of milling time. The Fe2O3milled 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 Fe2O3milled powders with a fine granulation.
