Study of Zn-Cu Ferrite Nanoparticles for LPG Sensing

GAS SENSING PROPERTIES OF POROUS Cu-, Cd- AND Zn- FERRITES

Some spinel ferrites, MFe2O4 (M = Cu, Cd and Zn), having submicron grain sizes (0.1–0.7μm) were prepared by sol-gel-selfcombustion and their sensing properties to reducing gases were investigated. The gas sensing characteristics were obtained by measuring the sensitivity as a function of various controlling factors, like operating temperature, composition and concentration of the gas, and final...

Green Synthesis and Characterization of Ni-Cu-Mg Ferrite Nanoparticles in the Presence of Tragacanth Gum and Study of Their Catalytic Activity in the Synthesis of Hexanitrohexaazaisowurtzitane

Here, we report the synthesis, characterization, and catalytic evaluation of Ni-Cu-Mg ferrite using tragacanth gum as biotemplate and Metals nitrate as the metal source by the sol-gel method without using any organic chemicals. The sample was characterized by powder X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Vibrating Sample Magnetometer (VSM), and Scanning El...

The Effects of Cu and Zn Dopants on Phase Constituents, Magnetic Properties and Microstructure of Nickel Ferrite

In this research nanoparticles of Ni0.55Zn0.35Cu0.1Fe2O4 were synthesized by sol–gel auto-combustion method. Changes in phase constituents, microstructure and magnetic properties as a result of Zn and Cu additions were evaluated by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), and Vibration Sample Magnetometer (VSM) techniques. XRD results show that the doped sam...

Low temperature-fired Ni-Cu-Zn ferrite nanoparticles through auto-combustion method for multilayer chip inductor applications

Ferrite nanoparticles of basic composition Ni0.7-xZnxCu0.3Fe2O4 (0.0 ≤ x ≤ 0.2, x = 0.05) were synthesized through auto-combustion method and were characterized for structural properties using X-ray diffraction [XRD], scanning electron microscopy, transmission electron microscopy, and Fourier transform infrared spectroscopy [FT-IR]. XRD analysis of the powder samples sintered at 600°C for 4 h s...
