“…One of the main challenges for the synthetic methods is to produce materials with a good particle size distribution and desired composition uniformity, structure and crystallinity [8]. It was recently shown that the coprecipitation approach is the simplest, most useful [9], widely used [10], most efficient, and the least expensive [11] method for the preparation of ferrous oxide nanoparticles. Additionally, it allows control over the particle size and morphology [12].…”

A series of Mn x Fe 3−x O 4 (0 ≤ x ≤ 1) nanoparticles was successfully synthesized via a simple coprecipitation method. The starting material was a natural magnetite purified from local iron sand. Crystallite nanoparticles were produced by drying without using a high calcination temperature. Rietveld analysis of the X-ray diffractometry (XRD) data for all samples demonstrated that the Mn ions partially substituted the Fe ions in the spinel cubic structure of the Fe 3 O 4 to form Mn x Fe 3−x O 4 phases. We applied two lognormal spherical and single mass fractal models to the analysis of the small-angle neutron scattering (SANS) data and revealed that the primary Mn x Fe 3−x O 4 particles ranged in size from 1.5 to 3.8 nm and formed three-dimensional Darminto

“…A simple method to produce Fe 3 O 4 nanoparticles via coprecipitation method has been introduced using a local natural iron sand from Indonesia as a starting material. This coprecipitation method is considered to be the easiest method for preparing Fe 3 O 4 nanoparticles [12] because of its simplicity, efficiency, and inexpensiveness [13]. The use of starting material from commercial product can be substituted by natural iron sand.…”

Nanoparticles of Fe 3 O 4 have been successfully synthesized using a simple coprecipitation technique from natural iron sands, employing HNO 3 and NH 4 OH as dispersing and precipitating agents, respectively. The substitution of Fe with Mn to result in Fe 3x Mn x O 4 (0 ≤ x ≤ 3) was conducted to control the magnetic strength of this nano-sized spinel powder. It is shown that magnetic properties depend not only on the particle size and Mn doping but also on the particles clustering. The applications for magnetic fluids, gels, and coating are extensively described. Meanwhile, the spinel MgAl 2 O 4 nanoparticles have also been prepared by the same simple method from commercial starting materials. This powder was used as a nano-reinforcer of Al-matrix composites. In addition, MgAl 2 O 4 micro-sized powder forming a thick layer was successfully grown by electroless plating on the interface of matrix-filler in Al/SiC composites. The strengthening of mechanical properties with respect to the varying uses of these MgAl 2 O 4 powders is discussed.

“…Recently, several methods were used to synthesize highly crystalline and uniformly sized magnetic nanoparticles of mixed ferrite [2,3]. Most of these methods cannot be applied to a large scale and economic productions, because they require expensive and toxic reagents, complicated synthetic steps, high reaction temperature and long reaction times.…”

Nanocrystalline Al doped nickel-cobalt ferrite [Ni 0.6 Co 0.4 Fe 2-x Al x O 4 (x = 0.0, 0.1, 0.3, 0.5 and 0.7)] powders have been synthesized by sol-gel auto-ignition method and the effect of non-magnetic aluminum content on the nanosize particles and magnetic properties has been studied. The X-ray diffraction (XRD) revealed that the powders obtained are single phase with inverse spinel structure. The calculated grain size from XRD data have been verified using transmission electron microscopy (TEM). TEM photograph shows that the powders consist of nano meter sized grain. The size of nanoparticles decreases as the non magnetic Al content increases. Magnetic hysteresis loops were measured at room temperature with maximum applied magnetic field of 20 KOe. As aluminum content increases, the measured magnetic hysteresis curves became narrow and saturation magnetization (M s ), and coercive force (H c ) decreased. The reduction of magnetization with the increase of aluminum content is caused by non-magnetic Al 3+ ions and weakened interaction between sub-lattices.
