Abstract
Members, such as bearings, gaskets, electrical conductors and the like, as well as containing coatings, made from graphite intercalated with a metal halide exhibit superior stability except when used or stored in an extremely humid atmosphere. In a humid atmosphere these members and coatings tend to swell, crack and develop a corrosion layer over time. In accordance with the present invention, however, members and coatings made from intercalated graphite mixed with from 2 vol. % to about 30 vol. % of a metal powder do not exhibit this environmental instability.
