How it is made

Artificial graphite is produced by heating carbon compounds or carbon powder to 2500-3000 °C.

Production processes are divided into two groups: those employing partial combustion (furnance black process, Degussa gas black process, channel black process, lamp black process) and those based on pure pyrolysis (thermal black process, acetylene black process, Huls arc process). (Carbon black)

Animal charcoal, obtained by charring bones, meat, blood, etc... Activated charcoal, eg, carboraffin, norit, opocarbyl, ultracarbon, (are) prepd from wood & vegetables
