Abstract
A novel type of carbon filaments grow from a purified graphite material when the purified graphite material is heated in a plasma. The carbon filaments thus obtained can be converted into softer graphite filaments. Both the carbon filaments and the graphite filaments as such are extremely useful due to their excellent mechanical strengths. In addition, from each of them, intercalation compounds with an alkali metal can be obtained, which are useful not only as a highly conductive material but also as a catalyst for various reactions.
