| Research Abstract |
A synthesis process which can provide magnetic iron oxide(magnetite) nanoparticles under environmentally friendly conditions has been developed. In this process, a horizontal tumbling ball mill, which is industrially used as a grinding machine for micronization of particulate materials, is used as a reactor. The formation of magnetite was analyzed through the synthesis experiments and the numerical simulation of balls behavior in the mill. As a result, the reaction mechanism was clarified and the sizes of primary particles and aggregates could be controlled.
