Abstract
The positions of the K-absorption edges of iron are recorded for five crystals: Fe 0.885O, Fe 0.905O, Fe 3O 4, Fe 2O 3 and Fe metal, and for two amorphous solids: oxide glass ([Na 2O · 2SiO 2] 0.8 [Fe 2O 3] 0.2) and metallic glass (Fe 36Cr 32Ni 14P 12B 6). It is observed that there is a correlation between the positive X-ray K- absorption edge chemical shift and the effective coordination charge. The ionic state of iron in oxide glass is identical to the ferric iron in Fe 2O 3 as shown by the same positions of iron K-absorption edges in this glass and Fe 2O 3. The K-edge of the metallic glass appears 6.5 eV higher than that of the pure iron edge, which suggests that the bonding of iron in metallic glass is different from the pure iron metal.
