Synthesis of cobalt ferrite nanoparticles using combustion waves

Combustion synthesis of cobalt ferrite nanoparticles—Influence of fuel to oxidizer ratio

“…Among the various control parameters in a combustion process, fuel plays an important role in determining the morphology, phase, and particulate properties of the final product. Many researchers have reported combustion synthesis of CoFe 2 O 4 nanoparticles [7,[10][11][12][13][14]. It reveal that only glycine as a fuel was preferred to initiate the combustion reaction because of its high negative combustion heat (−3.24 kcal g −1 ) as compared to urea (−2.98 kcal g −1 ) and citric acid (−2.76 kcal g −1 ) [15].…”

Microwave absorbent properties of nanosized cobalt ferrite powders prepared by coprecipitation and subjected to different thermal treatments

“…Different synthesis methods, such as coprecipitation [8], electrochemical [9], hydrothermal [10], combustion [11] or mechanical alloying [12] are used to produce cobalt ferrite. Among the reported methods, the coprecipitation method is an efficient and economical way to mass production of ultrafine cobalt ferrite powder.…”

Enhancement of the crystal size and magnetic properties of Mg-substituted Co ferrite

“…Cobalt ferrite (CoFe 2 O 4 ), with high magnetocrystalline anisotropy and a remarkable chemical stability, is one of the most promising candidates for biological applications that require magnetic nanoparticles, ranging from recording media to photomagnetics [1], magnetic resonance imaging (MRI) and magnetic fluid hyperthermia (MFH) [2][3][4]. The physical properties of Co ferrite can be classified as those of hard ferrite in spite of its character as soft ferrite due to its relatively high coercivity and moderate magnetization which make its nanoparticles suitable for magnetic recording applications such as audio and videotape and high-density digital recording disks [5][6][7].…”
