This paper reports a simple and novel process for preparing nano-granular Zn(x)Fe(3-x)O(4) ferrite films (0 </= x </= 0.99) on Ag-coated glass substrates in DMAB-Fe(NO(3))(3)-Zn(NO(3))(2) solutions. The deposition process may be applied in preparing other cations-doped spinel ferrite films. The Zn content x in the Zn(x)Fe(3-x)O(4) films depends linearly on the Zn(2+) ion concentration ranging f...

Ferrite nano particles of basic composition Ni Cd Smx Fe2-xO4(0.0 ≤ x 0.05, X=0.01) where synthesized by citrate-gel auto combustion method have investigated. X-ray diffraction profile indicates that the samples are in single phase structure for sample without Sm content. For with ions, some peaks appeared which belongs to orthorhombic further, XRD been used calculated lattice parameter, densit...

The microstructure, mechanical properties, and hydrogen permeation behavior of hot rolled enamel steel were investigated. Three coiling temperatures were adopted to gain different sizes of ferrite grain and TiC precipitates. The results show that a large number of interphase precipitates of nano-sized TiC can be obtained at coiling temperatures of 650 and 700 °C, while a few precipitates are fo...

Glycerol mono-oleate (GMO) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of CoFe2O4 nano-particles by surfactant-assisted microwave method. Fourier transform infrared spectroscopy (FT-IR), X-Ray diffraction (XRD) and scanning electron microscopy (SEM) were used to consider the structural and...

Cobalt-doped iron oxide nanoparticles were prepared by solution combustion technique. The structural and magnetic properties of the prepared samples were also investigated. The average crystallite size of cobalt ferrite (CoFe2O4) magnetic nanoparticle was calculated using Scherrer equation, and it was found to be 16±5 nm. The particle size was measured by transmission electron microscope. This ...

Magnetic oxides are naturally occurring minerals. In order to understand their unique properties and their utilization in technological applications, one must fully understand the correlation between chemistry, structure, particle size and processing. Among the broad classification of magnetic oxides, the spinel ferrites gain much importance because of their low cost, high magnetic permeability...
