Graphite manufacturing process [SubsTech]
Jun 13, 2020 Pyrolytic graphiteis a form of graphite produced by high temperature decomposition of hydrocarbon gases in vacuum followed by deposition of the carbon atoms to the substrate surface The process is called Chemical Vapor Deposition (CVD)Impervious graphite for process equipment applications is manufactured in two main steps First synthetic graphite is manufactured Then this material is impregnated with phenolic resin to make it impervious and enhance its mechanical characteristicsGraphite manufacturing process GAB NeumannA process for the heat treatment of carbonaceous material in a reactor comprising electrodes located at both ends of the reactor, in which, in addition to the carbonaceous material to be treated, a functional charge of particulate graphite material is added to the reactor to allow the electric current to flow through the charge, with the proviso that when the carbonaceous material to be EST3 Graphite powder production and treatment
