nano-structured lanthanum strontium cobalt ferrite, la0.6sr0.4co0.2fe0.8o3 (lscf), was successfully synthesized via co-precipitation method using metal nitrates as starting materials. effects of precipitating agent and calcination temperature on the phase composition and morphology of synthesized powders were systematically studied using x-ray diffraction (xrd) and field emission scanning elect...

the synthesis of nano- structured cobalt through a controlled chemical process followed by heat treating at various temperatures is studied. the product is characterized by icp, xrd, fesem , and tem, indicating that the as- synthesized particles have an amorphous structure with 1.76 for co/b ratio, an average size of 50 nm. the transformation of intermediate phases into single phase nano- cryst...

this study is concerned with the synthesizing of cu-zn nano-ferrite particles in the laboratory applying simple techniques. the morphology of the synthesized nano-particles was analyzed using transmission electron microscopy (tem), and the minerals were identified using x-ray diffraction (xrd). the nano material was used to replace 1- 4 percent by weight of portland cement in cement pastes and ...

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...

The particle size distribution of the resultant cobalt ferrite samples was determined from Scanning Electron Microscopy (SEM) images using the granulometry image analysis method. Results showed the nanosized particles of the samples. The X-Ray Diffraction (XRD) patterns of samples were also analyzed by Rietveld refinement method. The results indicated that the precipitated sample at 95 <sup...

Nano-particles of polycrystalline Zn Fe2 O4 are prepared using sol-gel method with Ni, and Sm. They are obtained as dried gel after the successful chemical reaction of their respective metal nitrate solutions in the midst of citric acid as catalyst. Synthesis of materials is confirmed using XRD from the report of single phase polycrystalline ferrite material. The magnetic properties of Zn-ferri...
