“…The phase evolution for the produced samples was implemented by X-ray diffraction (XRD) on a Brucker axis D8 diffractometer using Cu-Kα (λ =1.5406) radiation and secondary monochromator in the range 2θ from 10° to 80° operating at 40 kV and 30 mA at a rate of 2°/min. The crystallite sizes of the produced BFO and BMO samples for the most intense peak plane determined from the X-ray diffraction data using the Debye-Scherrer formula [12,13]:…”

Nanocrystalline bismuth ferrite BFO; BiFeO3 and manganese sillenite, BMO; Bi12MnO20 (BMO) powders have been successfully elaborated using a facile co-precipitation approach. The formed materials were examined using X-ray diffraction analysis (XRD), field emission scanning electron microscopy (FE-SEM). Furthermore, the change in the optical properties was performed based on Fourier transform infrared spectroscopy (FT-IR) and UV-visible spectrophotometer. Typical, pure BiFeO3 and Bi12MnO20 phases were detected for the precursors precipitated at pH 10 based on ammonium hydroxide as a base then annealed at 500°C for 2h. Eventually, the optical band gap energy of BFO and BMO using Kubelka–Munk function based on Tauc’s plot was found to be 2.12 and 2.79 eV, respectively.

W-hexaferrite BaCo2Fe16O27 was prepared using the citrate nitrate combustion method. The sample was characterized using XRD, SEM, EDX and elemental mapping. XRD confirmed that the sample was synthesized in a single phase hexagonal structure with an average crystallite size 37.39 nm. SEM images of the sample show a spongy morphology with the agglomerated grain owing to dipole interaction between the crystallites. The magnetic properties of BaCo2Fe16O27 were studied using H-M hysteresis loop and the DC magnetic susceptibility. The sample has a ferrimagnetic behavior with saturation magnetization 64.133 emu/g. The magnetic properties of BaCo2Fe16O27 are originated from the Fe3+–O–Fe3+ superexchange. The synthesized sample is used as an adsorbent to remove the heavy metal Pb2+ from water. BaCo2Fe16O27 has Pb2+ removal efficiency 99% and 28% at pH 8 and 7 respectively. The Langmuir and Freundlich isotherms were used to analyze the experimental data. The Freundlich adsorption isotherm fitted the experimental data well.

Lithium ion substituted hexagonal strontium ferrite (Sr 1-x Li 2x Fe 12 O 19, where x= 0.1, 0.2, and 0.3) powders have been felicitously fabricated using tartrate precursor scheme. The impact of the Li + content, as well as the annealing temperature on the phase evolution, microstructure and magnetic performance, was commanded by X-ray diffraction pro le (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). Single phase hexagonal ferrite was consummated at a Li + ratio of 0.2 and different annealing temperatures, from 1000 to 1200 o C for 2h. An impurity α-Fe 2 O 3 phase was noted at a high Li + concentration of 0.4 and 0.6 at all temperatures. The crystallo-aspects characteristics were altered with Li + content and annealing temperature. The microstructure of pure hexagonal ferrite sample visualized platelet like structure. A ne spherical shape displayed with platelet shape by enhancing the Li + content up to 0.4 and 0.6. EDX analysis emphasized Fe, Sr, O, and Li atoms spread between the plate and spherical shapes. Good saturation magnetization (Ms=60.88 emu/g) was realized for Li + content of 0.2 as the results of increasing the thickness of the nanoplatelet structure.
