Simulation of nanophase iron production in lunar space weathering

► Confirming an effective method in producing np-Fe0 contained in agglutinatic glass. ► Microwave heating (MWH) can reduce np-Fe0 from ilmenite with the size of 100s nm. ► Proposing a method to produce np-Fe0 on grain's surface similar to sputtering. ► Magnetron sputtering (MSP) can condense np-Fe0 with the size of 10s nm. ► Analogs with np-Fe0 in both phases could be relative easily prepared by MWH&MSP.
