Comparison of conventional and microwave sintering on Y-ferrite

Abstract

In this paper we are comparing the results of the conventional and microwave sintered samples of Zn2-Y(Ba2Zn 2Fe12O22) ferrite. Y ferrite sample was synthesized using the commercial solid-state reaction method. In CS process, the sample was sintered in muffle furnace at 1200°C for 6 h. In MS process, the sample was sintered at 1120 °C for 30 min in air at the rate of 10°C per min. X-ray powder diffraction revealed that a single phase rhombohedral structure with space group R3m (166) for both samples. The average grain size of CS sample is 1.5-2μm which is greater than MS sample. Magnetic properties also changed with the microwave sintering. These results demonstrate that the strong microwave method is an alternative way to synthesize high performance Y ferrite. © 2013 AIP Publishing LLC.
