摘要
A process for producing a graphite block from a plurality of graphitizable polymer films or a plurality of carbonaceous films separately obtained from graphitizable polymer films is described. The method comprises superposing the plurality of the graphitizable polymer films or the plurality of the carbonaceous films, and thermally treating the plurality of the graphitizable polymer films or the plurality of the carbonaceous films in a substantially compression pressure-free condition when the treating temperature is in thermal decomposition temperature range and the graphitization temperature range and under compression pressures in temperature ranges between the thermal decomposition temperature and the graphitization temperature ranges and over the graphitization temperature range. The compression pressure over the graphitization temperature range should be higher than that in the range between the thermal decomposition and graphitization temperature ranges. By this, a wrinkle-free graphite block with a good rocking characteristic is obtained.
