Structural, Electrical, and impedance spectroscopy studies of Barium substituted nano calcium ferrites synthesized by solution combustion method.
Barium substituted nanocrystalline ferrites with chemical composition BaxCa1-xFe2O4 (x =0.0 to 0.25) BCAF were prepared by solution combustion method. The phase formation of mixed spinal structured ferrites was confirmed by PXRD analysis. The average crystallite size was calculated using Debye-Scherrer formula and it was found to be in the range of 27-44 nm. Surface morphology was analyzed by S...
متن کاملMagnetic Properties of Sr-Ferrite Nano-Powder Synthesized by Sol-Gel Auto-Combustion Method
In this paper, strontium ferrite (SrO.6Fe2O3) was synthesized by the sol-gel auto-combustion process. The thermal behavior of powder obtained from self-propagating combustion of initial gel was evaluated by simultaneous differential thermal analysis (DTA) and thermo gravimetric (TG), from room temperature to 1200°C. The as-burnt powder was calcined at various temperatures from 700-900°C to achi...
متن کاملStructural , Dielectric and Magnetic Behavior of Cu 2 + Substituted Ni - Zn Ferrite by Auto - combustion Technique
Structural and magnetic properties of Cu 2+ substituted Ni0.8-xCuxZn0.2Fe2O4 ferrites for x = 0.0 to 0.6 with the step increment of 0.2 prepared by an auto-combustion method have been investigated. The X-ray diffraction pattern of these compositions confirmed the formation of the single phase spinel structure. Further, the XRD have been used to calculate the lattice parameter and grain size. Th...
متن کاملStructural, Magnetic and Acetone Sensing Properties of Barium- Calcium Hexaferrite Synthesized by Sol- Gel Auto Combustion Method
In this research, barium calcium hexaferrite (Ba1-xCaxFe12O19 , 0≤x£1) nanoparticles were synthesized through a sol-gel combustion method. The dried gel samples were then calcined at 950ᵒC for 4:30h. The phase and microstructural evolution of calcined samples were investigated by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM), respectively. The results revealed formation ...
متن کاملMicrostructural and Mössbauer properties of low temperature synthesized Ni-Cd-Al ferrite nanoparticles
We report the influence of Al3+ doping on the microstructural and Mössbauer properties of ferrite nanoparticles of basic composition Ni0.2Cd0.3Fe2.5 - xAlxO4 (0.0 ≤ x ≤ 0.5) prepared through simple sol-gel method. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray, transmission electron microscopy (TEM), Fourier transformation infrared (FTIR), and Mössbauer spe...
