Abstract

Study of the magnetic material, Barium Hexaferitte, has been done by metallurgic powder. The magnetic material has been produced from fusionning of row material BaCO3 and Fe2O3, continuing by calcinations process of the temperature of 13000C, isotropic compaction and sintering process. The results of microstructure study show that sintering process has influence very significance for materials coersivity. The beginning of granular fusion process was at the temperature of 11000C, but this process was not complete that was indicated by still very small the intrinsic coersivity. The maximum coersivity was up to 112. 236 kA/m, that has been obtained at sintering temperature of 11500C. At this temperature, the granular fusion was forward to complete, but new phase has been formed in the material.
