%X Abstract Porous sphere-shaped magnesium (MgFe2O4) spinel ferrite particles were synthesized with high yields, crystallinity and purity through an easy, quick, reproducible and low-temperature hydrothermal synthesis route starting from an aqueous suspension of coprecipitated metal oxalates. The structural and morphological properties of the prepared materials were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, infrared spectroscopy and N2 adsorption¨Cdesorption measurement. Results show that the obtained MgFe2O4 particles are nearly spherical in shape and about 100-250 nm in mean diameter. Every magnetic microsphere is made of many ultrafine MgFe2O4 nanoparticles and porous in structure. The obtained sphere-shaped products exhibited a saturation magnetization of 70.25 emu/g and a coercivity of 326.41 Oe at room temperature
