In this work, a very facile onepot hydrothermal synthesis approach has been developed for the preparation of ultrathin magnetite nanoplates. The hydrothermal procedure was performed by aging ferrous hydroxide under anaerobic conditions, which is known as Schikorr reaction.
Magnetic particles are also supplied in a wet suspension such as water or oil. The wet magnetic particle testing method is generally more sensitive than the dry because the suspension provides the particles with more mobility and makes it possible for smaller particles to be used since dust and adherence to surface contamination is reduced or eliminated.
Co precipitation from aqueous solutions has been used in most of the methods, although other liquid solvents can also be used. A range of 30 to 100nm Spherical magnetite parti cles can be obtained by the reaction of a Fe(II) salt, a base and a mild oxidant (nitrate ions) in aqueous solutions[31].
Synthesis and characterization of Dendrimer modified Magnetite nanoparticles and their Antimicrobial activity for Toxicity analysis Interest has been shown in iron magnetite nanoparticles because of its various important properties such as large surface area with high surfacetovolume ratio, ease of separation, water solubility, super ...
Immediately following the synthesis, carbonatesubstituted (Btype) hydroxyapatite particles are mechanochemically synthesized by wet milling dicalcium phosphate dihydrate and calcium carbonate in a dispersed suspension of magnetite nanoparticles, during which the magnetite nanoparticles are incorporated into the hydroxyapatite matrix.
