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.
