Cost-effective and controllable synthesis of M0.25Ni0.15Cu0.25Co0.35Fe2O4 (M2+ = Mg2+, Mn2+, Cd2+) ferrites via the sol–gel auto-combustion technique. The impact divalent cations on structural, dielectric, optoelectrical properties was examined by XRD, FTIR, Raman, LCR, UV–Vis, two probe I-V measurement techniques. crystallite size 52.66 nm, minimum specific surface area observed 5.1507 m2/g fo...

The aim of this study is to evaluate the influence of pH on the synthesis of nanocrystallines cobalt ferrite by combination of sol- gel auto combustion and ultrasonic irradiation methods. Two different fuels, urea and thiourea, along with metal nitrates (oxidant) were used to prepare CoFe2O4 powders. The morphology of the resulting powders was investigated. The powders wer...

The synthesis of CaCO3/Cu2O/GO nanocomposites was developed by sol-gel auto-combustion method. analysis structure completed on X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and environmental scanning electron microscopy (ESEM). XRD spectra the matched crystal CaCO3/Cu2O. average size 20 nm for Cu2O 25 CaCO3 nanoparticles. FTIR data showed absorptio...

Cu and Ni ferrites as the semiconductor materials were synthesized by a microwave sol-gel auto-combustion method. Two cationic surfactants, sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB), were applied and the influence of surfactants on the properties of the Cu and Ni ferrite particles was studied. The samples were characterized by X-ray powder diffraction (XRD) pattern,...
