Abstract

名古屋大学年代測定総合研究センターシンポジウム報告

It is well known that age of ancient iron artifacts can be measured by using carbon contained in the iron artifacts. A RF furnace has been normally used to melt and oxidize the iron artifacts and to extract carbon from them as a form of CO2. This method, however, requires an expensive equipment and takes time for carbon extraction. As an another method, normal quartz tube is used for metal iron combustion at the temperature of 1000℃ for about 15 hours. We tested the quartz tube method of metal iron combustion successfully for metal iron in fine fragment forms. Almost 100% recovery was attained when metal iron weight is less than 15% of CuO that is used as an oxidizer. As a second stage of our experiment, we are planning to combust a big lump of metal iron.
