Outline of Final Research Achievements

The carbon dioxide in the iron and steel industries accounts for about 5% of the total world emission because of the use of coal as reductant, heat source, carburization and so on. Most of research projects for reduction of carbon dioxide are still depend on the carbon as reductant and it is difficult to reduce much amount of emission. Recently we found that several kinds of ceramics which do not include carbon could reduce iron-oxide with in-situ electron microscopy. Some of reactions were promoted by high energy electron irradiation. The observation of these reactions enabled by the development of the way of specimen preparation. These reaction systems do not generate carbon dioxide and these results are expected to apply for low carbon dioxide emission iron-making process.
