VERFAHREN ZUR HERSTELLUNG VON CARBONISIERTEN ODER GRAPHITIERTEN FORMTEILEN
A method for producing carbonized or graphitized molding parts is particularly simple to implement and also allows producing complex molding parts without mechanical post-processing. This is achieved by the production of a pourable liquid polymer mixture which is as homogenized as possible, consisting of a carbon granulate, pitch, soot or graphite powder and polyacrylnitrile dissolved in a solvent, filling the liquid polymer mixture into a casting mold and immersing the filled casting mold in water over a predetermined period of time until the polymer mixture is sufficiently cured and dimensionally stable, and subsequent breaking of the casting mold and stabilizing the prefabricated cured molding part by uniform heating up in a furnace in air at a predefined temperature for stabilizing and degassing volatile constituents, and performing a high-temperature treatment for carbonizing or graphitizing the molding part in a furnace under protective gas.
