Abstract

Hollow carbon bodies, particularly tubes, containing at most 3% by weight hydrogen, are made by centrifugally casting phenol-aldehyde resin and carbonizing by heating cycle (a) or (b): (a) to 600 DEG C. at 5 DEG C. per hour, to 825 DEG C. at 10 DEG C. per hour, to 1400 DEG C., preferably at least 1600 DEG C., at 20 DEG C. per hour maintaining the maximum temperature for 24 hours, and cooling to room temperature at 20 DEG C. per hour; (b) to 500 DEG C. at 1 DEG C. per hour, to 900 DEG C. at 5 DEG C. per hour, cooling naturally to room temperature, reheating in vacuo or in an inert or reducing atmosphere to at least 1600 DEG C. at 20 DEG C. per hour and cooling naturally to room temperature. Both cycles are disclosed in Specification 956,452. In an Example, a liquid resole resin was centrifugally cast in a P.T.F.E.-lined stainless steel mould at 2000 r.p.m., externally heated to 90-100 DEG C. for 15 hours, removed from the mould, further cured at 110 DEG C. and carbonized by cycle (a).
