Formation and Magnetic Characterization of Magnesium Oxide / Iron Nano Composite Particles
Nano-sized composite magnetic particles MgO /Fe were in-situ combustion synthesized at 620°Cfor the Mg-70.9wt%Fe3O4 system. In this paper, we discussed the reactant ratio on the influence of micro-morphology and the magnetic properties of nanoparticles. It was indentified that: Mg(29.1wt%) was the suitable reactant ratio, the sintered composite spherical particles with mean diameter 40nm distributed evenly, particles had good soft magnetic properties, and it was the future drug carriers materials.
