FORFARANDE FOR FRAMSTELLNING AV FORMADE ALSTER AV HODENSITETSGRAFIT

摘要

A process for the production of shaped articles of high density graphite having excellent mold-releasing property which comprises incorporating amorphous carbon powder such as powdery coke or artificial graphite powder with about 3-20% by weight of boric acid or boron oxide as a sintering-promoting agent, and baking the mixture under a pressure of 150-500 kg/cm2 without the aid of a binding agent such as pitch. Shaped articles of high density graphite possessing excellent mechanical strength are obtained by this process.
