ABSTRACT:
An electrode for medical applications can be manufactured with different geometries, and particularly in the form of hollow bodies, by depositing pyrographite on a shaped body of glassy carbon. The deposition is achieved by means of the pyrolysis of hydrocarbons at temperatures ranging approximately from 1800.degree. to 2100.degree. C. After cooling, the pyrographite coating is removed from the shaped body and a pyrographite electrode is produced from the coating.
