Abstract
The hollow BaFe12O19 submicron spheres (HBSSs) for advanced functional magnetic materials were synthesized successfully by self assembly method using diethyleneamine (DEA). The optimized concentration of DEA surfactant was found to be 1.1 mL with pH > 12.2 for the elaborate hollow sphere structure. The coercivity and remanence properties of HBSSs with 500-nm-sized showed 4.2 kOe (iHc) and 2.2 kG (Br), respectively. These results revealed that HBSSs particles were successfully synthesized to submicron size with the quantitative compounding of barium and ferrite precursors.
