My experiment is about iron nanoparticle and the material was 99.9% iron wire. After the nanoparticle was made, due to the signal on XRD was not strong enough the nanoparticle was condensed and I received Fe2 result from XRD analysis.
I did some research and couldn't figure out what Fe2 meant and how can it be applied on.
Could anyone help me? Thank you so much!
Any system of parallel crystal planes with Miller indices h, k, l is characterized by an interplanar spacing d. The distance between the planes can be found using the Bragg equation and the ХRD. The crystal modification of iron - α-Fe - has a body-centered cubic lattice with distances between the planes of 0.287 nm. Fe2 has a distance between nuclei of 0.187-0.202 nm. Why did you decide that there are reflexes of the Fe2 molecule on the diffractogram?
