PRODUCTION OF CARBON SPHERULE BY HIGH-PRESSURE CARBONIZATION OF NORMAL PARAFFIN

摘要

PURPOSE:To efficiently obtain carbon spherules having uniformity and constant quality by a relatively simple method, by carbonizing a normal paraffin in a supercritical state. CONSTITUTION:A solid normal paraffin which is a liquid or solid at ordinary temperature is thermally decomposed at a high density in a supercritical state at =500 deg.C under pressure of an inert gas or its own atmospheric gas to afford carbon spherules having 1-10mum particle diameter and smooth surface.
