ABSTRACT:
In the preferred embodiment, graphite fibers that are 5 to 15 microns in diameter and up to several centimeters long are grown within a thin-walled stainless steel tube by flowing natural gas through the tube, concurrently contacting the outer tube surface with wet hydrogen gas and heating to between 925.degree. C. to 1075.degree. C. to decompose methane in the natural gas to grow fibers on the inner surface of the tube.
