摘要：

In this study, the mineral material addition of FeMn and FeB to the hematite (alpha-Fe2O3) by varying each mass concentration of 0, 4, and 8 wt.% have been prepared by powder metallurgy method. The mixing process of the powder was done by high energy milling (HEM) for 1 h. Then, the powders were calcined at temperature of 1000 degrees C for 2 h. The Effect of FeMn and FeB additives on alpha-Fe2O3 causes the increasing of the particles diameter. The increasing of FeMn additive increases the powder density of material, but the addition of FeB decreases it. The material of alpha-Fe2O3 with FeMn additive has dominant phases of alpha-Fe2O3 and the minor phases of MnO2 and Fe2O3. The material of alpha-Fe2O3 with FeB additive has two phases as magnetite (Fe2O3) and hematite (alpha-Fe2O3). The magnetic properties of a alpha-Fe(2)O(3)material with FeMn and FeB additives decrease the saturation value and coercivity.
