| Research Abstract |
In the present year, following new experiments were carried out and several new results were obtained. Those resu lts will be published in the future.
The new experiments
(1) Carbon ion implantation into hematite was carried out.
(2) XPS measurement on the hematite was carried out to clarify the variation of chemical bonding among Fe-C-O.
(3) In situ observation of high temperature behavior of the carbon implanted into hematite were preformed.
From these experiments, Chemical bonding among Fe-C-O atoms in the hematite were gradually changed from the surface. The existence of C-C bond showed a maximum value around 1μm to 2μm, the proportions of C-O bonding and C=O bonding were relatively high. In the region deeper than 2μm, Fe-C bonding was increased, which meant that the carbon implanted into hematite increased the interaction with Fe atom rather than O atom.
