Abstract:

In the present work, the synthesis of Barium hexaferrite (BaFe12O19) nanoparticles in thepresence of a large excess amount of OH− anions by the hydrothermal method in the presence and absence of surfactants such as Sodium dodecyl benzene sulfonate and Triton X-114 was reported. The optimized temperature in the absence of surfactant was determined (200 °C) and then Barium hexaferrite nanoparticles were synthesized by assistance of surfactants at this temperature. In this way, it was confirmed that the secondary re-crystallization can be totally suppressed with the use of surfactant and addition of surfactant leads to the synthesis of uniform and ultrafine nanoparticles with excellent superparamagnetic properties. Barium hexaferite nanoparticles have a disc-like shape. The structure, morphology and magnetic properties of samples were characterized and investigated by Powder X-ray Diffraction (PXRD), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM) techniques.

Keywords:
