Leitendes, expandierbares Kohlepastenmaterial.

摘要

An expandable carbonaceous paste comprising natural graphite flakes and expandable graphite flakes, such as acid treated graphite flakes, mixed with a hydrocarbon viscous liquid such as tar so that when the paste is exposed to heat, the paste will expand and have good thermal conductivity characteristics and then upon further heating the paste will convert to a rigid carbon structure.
