Title: RIETVELD STRUCTURE REFINEMENT OF NEW MINERAL LUOBUSAITE(β-FeSi_2)
Abstract: Luobusaite(β-FeSi2)(IMA2005-052a)is a nature Si-Fe alloy new mineral with formula Fe0.83 Si2.00.The crystal structure was refined by the Rietveld method in space group Cmca,a=0.983 62 nm,b=0.783 01 nm,c=0.786 55 nm,z=16,by using powder diffraction data obtained by a combination of CCD rotation patterns.The occupancy refinement showed that there was a lack of Fe,and it only occurred at Fe2 site.
