Microwave Sintering of Barium Ferrite Nanoparticles Processed via Sol-Gel Method

Abstract:

Consolidated barium ferrite nanoparticles were expected to obtain better magnetic properties. Sol-gel method was used to produce the barium ferrite nanoparticles. Various calcination temperatures were set to obtain the single phase structure. XRD pattern and SEM image confirmed the nanoparticles with 48.66 nm and 70 nm, respectively. Compacted samples were sintered using microwave sintering and conventional furnace with various temperature and time. Magnetic measurement test shows that microwave sintered samples have better properties. The highest magnetic properties values for microwave sintered sample is obtained at 950°C for 60 minutes with coercivity (Hc) of 5565 Oersted, remanence (Br) of 1537 Gauss and saturation magnetization (Ms) of 37.04 emu/g.
