ABSTRACT:
A method of producing high density carbon at relatively low temperatures is described. By flowing methane gas over glass rods or tubes at flow rates of 10 to 1300 cc per minute and temperatures of 1000.degree. to 1200.degree. C., carbon having a density greater than 2 grams per cubic centimeter and hydrogen gas are produced. An inert gas such as argon can be intermittently pulsed through the system to sweep the system free of low density carbon deposits and heating preferably takes place by means of induction coil heated graphite susceptors or resistance heaters.
