Abstract
A method of manufacturing a ferrous oxide nanoparticle includes a water removing step raising temperature of a solution containing an iron oxide, an organic acid dissolving the iron oxide, and a first solvent to a first temperature and removing water in the solution, a second temperature maintaining step raising the first temperature to a second temperature and maintaining the second temperature, and a particle extracting step extracting the ferrous oxide nanoparticle from the solution after the second temperature maintaining step.
