ABSTRACT:
The yield of good-quality bodies consisting of vitreous carbon is increased to substantially 100% when the pyrolysis is performed in a reaction vessel in which a collecting container or a collecting disc for the condensable volatile decomposition products which is open at its upper side is arranged above the polymeric substances to be pyrolized. The collecting disc divides the interior of the reaction vessel into two parts, a passage for gases remaining between the upper part and the lower part. During the pyrolysis, a spatial temperature distribution is adjusted in the reaction vessel which results in a pulsating evaporation and condensation of the decomposition products, so that the decomposition products are completely removed.
