| The magnetic and mechanical properties of sintered ceramic magnets with composition SrxBa1-xFe12O19 with mole fraction ratio (x) have been investigated. The SrxBa1-xFe12O19 with mole fraction ratio to adjust with x = 0, 0.25, 0.5, 0.75, and 1 were calcined at temperature of 1100 ?C. Subsequently, the calcined powder was compacted and sintered to form sintered pellets and bars. For determine of sintering temperature, mixture of hematite and barium carbonate was calcined at temperature 1100 ?C, compacted, and then sintered at various temperature of 1000, 1100, and 1200 ?C. The magnetic properties are determined by hysteresis curve that was established using VSM machine. X-ray diffraction was used to investigate crystal structure of the elements. The Archimedes principle was practiced to measure density of sintered products. The mechanical properties were examined using flexural strength and Vickers hardness. As a result of the research, increased of the fraction mole x would increase Ms of the SrxBa1-xFe12O19. At the x = 0 for SrFe12O19 and x = 1 for BaFe12O19 were the Ms of 41.14 emu/g and the Ms of 80.32 emu/g, respectively. Otherwise, increased of the mole fraction x would decreased Hc. The Hc of the SrFe12O19 more than the BaFe12O19 were of 3.64 kOe and 5.22 kOe, respectively. Whereas the BH max of 4.22 MGOe was highest of the x = 0.25 for the Sr0.25Ba0.75Fe12O19. The flexural strength and Vickers hardness did not change with increasing of the x mole fraction. However, the flexural strength and Vickers hardness increased with increasing sintering temperature. |
