- Abstract
This paper reports the eco-friendly synthesized BaFeO phase materials by a molten salt flux approach and their experimental findings. The reaction mixture (BaCO and Fe O ) annealed with the mixture of salt (NaCl:KCl) flux yielded good quality nanocrystalline hexagonal ferrite BaFeO phase materials. The plate-like hexagonal-shaped BaFeO phase morphology with random particle sizes of ∼370 to 940 nm is seen for the good quality flux-annealed sample. The room-temperature magnetic hysteresis loop of the BaFeO sample exhibits hard ferromagnetic saturation magnetization ( M ) of 50.23 emu/g at 15 kOe, and coercive field ( H ) is 3500 Oe. The determined energy bandgap ( E ) is found to be 3.58 eV for the BaFeO phase material. The Fourier transform infrared (FT-IR) spectral features confirm the presence of Fe-O and Ba-O bonds in the flux-synthesized BaFeO materials. The photoluminescence (PL) emission peak (∼360 nm) intensity of BaFeO materials varies regardless of annealing temperatures. The different salt flux-synthesized BaFeO materials appear as brown- and dark gray-colored powders that can be applied as a ceramic color pigment due to its high NIR reflectivity.
