ABSTRACT:
A material having a vapor pressure of at least 5 mm Hg at 490.degree.C. and selected from aromatic and cycloaliphatic hydrocarbons and alkyl derivatives thereof, nitrogen-, oxygen- and sulfur-containing compounds having hetero rings and alkyl derivatives thereof, substituted compounds of these compounds, and substances containing these compounds is used as starting material. Such starting material is brought into contact in a vapor state, if necessary, diluted with an inert gas, with a substrate heated at a temperature of 600.degree.-1500.degree.C. thereby depositing the resulting isotropic pyrolytic carbon on the substrate.
