Carbon materials are chemically inert in non oxidizing media. Under normal temperature and pressure, no chemical changes will occur. Except for long-term immersion in nitric acid, hydrofluoric acid, or in fluorine, bromine, and other strong oxidizing atmospheres, interlayer compounds will slowly form. It is not corroded by other acids, bases, and salts, and does not interact with any organic compounds. There is no significant oxidation phenomenon of graphite within 450 ℃ in the air. It only reacts with water vapor above 700 ℃ and with CO and CO2 above 900 ℃. The temperature at which graphite produces carbides with certain metal and oxide powders is mostly above 1000 ℃.

The chemical reactions of carbon materials can be divided into the following three types:

(1) Gasification reaction and high-temperature oxidation reaction;

(2) Solid solid reactions with metals, ceramics, etc;

(3) Formation reaction of interlayer compounds.
