A synthetic guide toward the tailored production of magnetic iron oxide nanoparticles

In the last decades, magnetic ceramics are very appealing materials that find applicationsin several technologic fields. Among these, iron oxides nanoparticles are the main relevantones due to their low-cost as naturally occurring substrates. However, depending on theapplication, it can be necessary to induce a specific shape and size control over the finalmorphology, and consequently a proper synthetic route becomes mandatory. Hence, thisdocument provides a summary of the main relevant chemical, physical, thermal, and bio-logical methods to induce a certain degree of morphological control in iron oxides. The mainfocus of this document relies on highlighting the principal guidelines, unveiling both advan-tages and disadvantages of each method in terms of morphology control in the resultingproducts. Lastly, a particular emphasis has been dedicated toward the industrial feasibilityof all processes here discussed.
