Hydrothermal Synthesis of Calcium Ferrites

Nanomagnetism in Hydrothermal Ferrites Probed by Mfm

Nanomagnetic structures of hydrothermal NiZn ferrites sintered at various temperatures was studied in this work through Magnetic Force Microscopy (MFM) using different magnetically characterized tips. The magnetic patterns varied according to the tip employed and were correlated to the magnetic induced field generated by these different coated tips. NiZn ferrites were produced at 200°C by hydro...

Synthesis and Characterization of Mixed Ferrites

In this work we prepare nanocrystalline mixed ferrites by equilibrated low entropy routes with generic formula of MnxNi1-xFe2O4. Two series of samples have been prepared where “x” varies as 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 the samples have been prepared by chemical co-precipitation route. For the first calculated amount of salts of Mn, Fe and Ni were dissolved in deionized water and stirred for ...

Synthesis and Structural Characterization of Nanomanganese Ferrites

The semiconductor spinel ferrite will have the chemical formula as AB2O4 (where A  divalent metal ion like Ni, Mn, Zn, etc and B  Iron metal ion Fe2 + and Fe3 +) and many studies have focused on the synthesis of nanomaterials because of extensive applications due to their novel properties. Magnetite and spinel ferrite nanocrystals are regarded as two of the most important inorganic nanomateri...

Hydrothermal synthesis nanoparticle bysupercritical fluid

Supercritical fluid (SCF) technology has become an important tool of materials processing in the lasttwo decades. Supercritical CO2 and H2O are extensively being used in the preparation of a great variety ofnanomaterials. The greatest requirement in the application of nanomaterials is its size and morphology control, which determine the application potential of the nanoparticles, as...
