PENINGKATAN SIFAT MAGNETIK MATERIAL HEMATIT MELALUI SUBTITUSI BARIUM DAN KONTROL TEMPERATUR SINTERING
Abstract: Ferrite magnet or
ceramic magnet is a competitive product in the magnet market due to low price,
corrosion resistant and chemically stable. Barium hexa-ferrite magnet is one of
ferrite magnet which is mostly used as magnetic storage and electronic devices
based on nanotechnology. Barium hexa- ferrites are synthetized through solid
state reaction method at sintering temperatures of 1100 °C with the composition
(100-x)Fe2O3 : xBaCO3 , where x = 0 and 20 in mol % . Results of XRD characterization
show that the diffraction peaks of XRD spectrum is dominated by the peaks of
barium ferrite crystal with a hexagonal crystal system. Magnetic properties of
Fe2O3 material doped with barium carbonate of 20 mol % and sintered at 1100 °C
increase significantly compared to the others. This simple and inexpensive
method is very promising for the manufacture of barium hexa-ferrite materials
with natural ferrite as the main material.
