Carbon is black powder or granular porous crystal. Boiling point 4827℃, 3652℃ sublimation, the relative density of about 1.8-2.1, the performance of the relative density of about 0.08-0.45.
Carbon is made from wood chips, branches, charcoal, nut shells, coal and other raw materials through carbonization and activation. Carbon containing materials in isolation of air conditions heating treatment, remove volatile components (water and part of the tar), the formation of large pores of carbon, further activation methods have two categories: 1. Steam, gas activation more commonly used activators are carbon dioxide and steam. 2. The activators of chemical activation method are carbonate, sulfate, nitrate, etc., which can emit gases (such as carbon dioxide and oxygen) at high temperature; Also available nitric acid, sulfuric acid, phosphoric acid and other acid oxidant. The method of treating carbon with zinc chloride solution has also been widely used.
