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

Synthesis of single-phase cobalt ferrite nanoparticles via a novel EDTA/EG precursor-based route and their magnetic properties

“…The CoFe 2 O 4 with an inverse spinel structure shows the ferrimagnetism that originates from the magnetic moment of the antiparallel spins between Fe 3+ ions at the octahedral sites and Co 2+ ions at the tetrahedral sites [10]. The hysteresis loops measured at room temperature for the samples 1 to 9.…”

“…These properties, along with its great physical and chemical stabilities, make CoFe 2 O 4 nanoparticles suitable for many practical applications such as magnetic fluid [1,2], drug delivery [3], high density digital recording disks and magneto-optical recording media [4,5,6]. The chemical processes used to prepare cobalt ferrite powder are very diverse from the using of the polymeric precursor [7,8], wet chemical route [9,10,11], and chemical coprecipitation techniques [12,13,14]. The sol-gel technique is one of the most proper methods for the synthesis of homogeneous nanocrystalline materials.…”

Influence of calcination temperature on Cd0.3Co0.7Fe2O4 nanoparticles: Structural, thermal and magnetic properties

“…Therefore the ferrite has attracted towards the cubic spinel-structured cobalt ferrite with variable particlesize [4]. However, the properties of these materials and their particle size have been greatly depends upon the method of synthesis and the annealing/sintering temperature [5][6][7][8][9][10][11]. The heat treatment implies to form the crystalline spinel structure by means of the inter-diffusion process.…”

Magnetic and dielectric properties of Fe3BO6 nanoplates prepared through self-combustion method

“…[23][24][25] In a theoretical stoichiometric composition, oxidizing valence provided by the oxidizer is equal to reducing valence from the fuel. The chosen fuel with high reducing valences coupled with high enthalpy of combustion 9.27 kcal/g assisted to reach the ignition temperature and complete the combustion in short duration of the reaction time.…”
