Synthesis and characterization of Nickel Copper Ferrite
Nano size nickel copper ferrite powders (NiCuFe2O4) have been prepared by a prepared by Co precipitation method. The resulting powders were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM).The result showed nanosize nickel copper ferrite(35.65nm). The powders showed extensive XRD line broadening and sizes of crystals observed from the XRD line broadening was35.65 nm,...
متن کاملSynthesis and Characterization of Nickel Zinc Ferrite Nanoparticles
In this research nickel zinc ferrite nanoparticles with composition of Ni1-xZnxFe2O4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °C for 5 hours. The structure of nanoparticles was studied using X-ray diffraction pattern. The lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticl...
متن کاملElectromagnetic and microwave-absorbing properties of magnetic nickel ferrite nanocrystals.
The electromagnetic and microwave absorbing properties of nickel ferrite nanocrystals were investigated for the first time. There were two frequencies corresponding to the maximum reflection loss in a wide thickness range from 3.0 to 5.0 mm, which may be bought by the nanosize effect and the good crystallization of the nanocrystals.

متن کاملSynthesis of ferrite and nickel ferrite nanoparticles using radio-frequency thermal plasma torch
Nanocrystalline ~NC! ferrite powders have been synthesized using a 50 kW–3 MHz rf thermal plasma torch for high-frequency soft magnet applications. A mixed powder of Ni and Fe (Ni:Fe 51:2), a NiFe permalloy powder with additional Fe powder (Ni:Fe51:2), and a NiFe permalloy powder (Ni:Fe51:1) were used as precursors for synthesis. Airflow into the reactor chamber was the source of oxygen for oxi...
