OSTI ID:4842585
A method is described for producing a shaped carbon body of density at least 1.69 g/cc from which a graphite body may be produced with a density of at least 1.75 g/cc. The method for the carbon bcdy consists of forming a shaped plastic mass of powdered carbon or graphite with a fusible cokable binder and baking at 800 to 1000 deg C to effect coking of the binder under a constant pressure of at least 100 psig, preferably 180 psig. The rate of heating to the maximum temperature is never greater than 6 deg C per hour. To obtain a graphite body from this process, the carbon shaped body is further baked to a graphitizing temperature, for example, 2000 to 3000 deg C. (N.W.R.)
