The liquid phase is vaporized by the laser melting in liquid, and a vapor layer is formed on the particle surface. The use of organic solvents in the liquid phase from triiron tetroxide or CuO as raw material is unclear as to the formation of reduced particles such as FeO, Fe, Cu and the details of the reaction. Therefore, in this study, we simulated what kind of phenomenon the organic solvent causes under a high temperature condition for a short time, suggesting the possibility of reduction of iron oxide by organic solvent as a result.
