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