“…As stated above, the particle size of ferrite powders is crucially dependent on the temperature during the heat treatment [16,17]. The observed increase in the size at higher temperatures could be a result of the formation of crystalline clusters, clusters of crystals which have become cemented together.…”

In the phase of the study reported, the sol-gel technique was followed in the preparation of cobalt ferrite amorphous powder following the same procedure which was selected as the best approach as described in a previous study. It was assumed that there must be a correlation between the heat treatment operational parameters and the structural properties of the material being synthesized. Similarly, it was understood that some heat treatment is necessary to completely decompose the organic and nitrate contents present in the amorphous powder. Having ensured that the heat treatment parameters could be changed without producing a material with poorer properties, it was then possible to produce batches of powders using milder conditions in the heat treatment operation. The particle size distributions of these new batches of nanoparticles were estimated to be in the range 7-28 nm and since the results showed promise, their magnetic properties were also determined.

“…Consequently, the variation observed in the value H c is not a property dependent mainly on the particle size. But, this behavior of H c may be related to the microstructure, the grain size, the residual magnetic induction, and other complex factors [44].…”

“…Most of these methods suffer with troublesome post-treatment and cannot be applied to a large-scale and economic production. Some researches [16,17] have prepared nanoparticles of CoFe 2 O 4 using auto-combustion method. It is noticed that this method stands out as an alternative and highly promising method for synthesis of CoFe 2 O 4 .…”

Cobalt ferrite (CoFe 2 O 4 ) nanoparticles were prepared through an auto-combustion method. The results of XRD show that the crystallite size of CoFe 2 O 4 nanoparticles increases from 57 to 105 nm with a slight change in lattice constant as the annealing temperature increases from 300 to 1200 C. The magnetic measurements by vibrating sample magnetometer (VSM) show that M s increases monotonously by increasing the annealing temperature from 300 to 1200 C and C hB and M s reached a maximum when annealing temperature is about 400 C due to the change of the grain size.
