Inductive heating synthesis is an emerging technique with the potential to displace the hot-injection synthesis method to prepare colloidal particles very rapidly with a narrow size distribution, controlled size, and high crystallinity. In this work, the inductive heating synthesis is applied to produce a short-temperature jump to mimic conditions like the hot-injection method to prepare traditional iron and iron oxide nanoparticles (IONPs) in the 3–11 nm size range within various solvents, precursors, and reaction time conditions. Moreover, this inductive heating technique can be used under unique experimental conditions not available for hot-injection reactions. These conditions include the use of very high initial monomer concentrations. Considering benefits over conventional methods, the inductive heating technique has the potential to provide an industrial level scale-up synthesis. The magnetization of these particles is consistent with the magnetization of the particles from the literature.

快速感应加热方法可控制尺寸的合成铁和氧化铁纳米颗粒。

感应加热合成是一种新兴技术，具有取代热注射合成方法的潜力，可以非常快速地制备具有窄尺寸分布，受控尺寸和高结晶度的胶体颗粒。在这项工作中，采用感应加热合成技术来产生短暂的温度跃迁，以模拟条件，例如热注入法，以在各种溶剂，前体中制备3–11 nm尺寸范围内的传统铁和氧化铁纳米粒子（IONP）。，以及反应时间条件。而且，这种感应加热技术可以在无法用于热注射反应的独特实验条件下使用。这些条件包括使用非常高的初始单体浓度。考虑到与传统方法相比的优势，感应加热技术具有提供工业规模放大合成的潜力。这些颗粒的磁化与文献中的颗粒的磁化一致。
