OSTI ID:4031785
A method for producing high-density carbon bodies with reduced permeability is given. The method consists of maintaining a temperature gradient within a performed permeable carbon ocdy, such that the surface is at a temperature below that at which cracking of a gaseous carbonizable compound occurs. Part of the body is at a temperature above that at which the cracking occurs. The gaseous compound is then supplied to the surface area. The carbon bcdy is in the form of a graphite rod or tube. For the tube the gaseous carbonizable compound, propane, is applied to the inner surface which is below the cracking temperature with the outer surface being above the cracking temperature. (N.W.R.)
