Abstract
Abstract Electrically conductive carbon compositions are disclosed which are formed from carbon having a graphite-like structure and a nitrosyl or nitronium salt or salts. The nitrosyl or nitronium salt reacts with the carbon to intercalate it with charge-exchange atoms or molecules. Binary, ternary and multi-intercalated lamellar compositions are produced according to the particular reaction process selected. The compositions may be used alone as electrical conductors or may be combined in a matrix to form composite conductors.
