Abstract
A coating of silicon carbide is formed on carbon filaments by passing the heated filaments into an atmosphere of hydrogen and silicon tetrachloride to deposit silicon, and then into a silicon carbide-forming atmosphere. Carbon filaments having a coating of silicon carbide up to 0.2 micron or over 10 microns thick are described.
