The Synthesis High Magnetization of Y2.7Bi0.3Fe4.7Mn0.3O12 Magnetic Powders with by Simplified Solid State Combustion Technique
Abstract
In this work, the preparation high magnetization of magnetic powders were study and the effects of calcination temperature (850-1150oC for 2 h) on the crystal structure, microstructure and magnetic properties of the Y2.7Bi0.3Fe4.7Mn0.3O12powders were investigated. The powders were synthesized by simplified combustion technique. Glycine was used as fuel. The crystal structure, microstructure, and magnetic properties of the powders were studied. It was found that the Y2.7Bi0.3Fe4.7Mn0.3O12 powders showed garnet structure with cubic and the pure Y2.7Bi0.3Fe4.7Mn0.3O12 powder was observed from the sample calcined at 1100oC for 2 h. The microstructure of the Y2.7Bi0.3Fe4.7Mn0.3O12 powders exhibited an almost spherical shape and an agglomerated form. The average particle size increased from 0.38 ± 0.10 to 1.98 ± 0.62 mm when calcination temperature increased from 850 to 1050oC. The particle of powder melt when calcination was higher temperature (1100-1150 oC for 2 h). The Ms value of Y2.7Bi0.3Fe4.7Mn0.3O12 powders with measuring at temperature of 300 and 50 K increased when calcination temperature increased. For the Mr value of Y2.7Bi0.3Fe4.7Mn0.3O12 powders, it was found that the change of the Mr value was no significant when the calcination temperature increased.
