Graphite chemical makeup

WebChemically, graphite is inert, resistant to heat, pressure, and does not react with water or air at standard temperature. However, at very high temperatures and strong oxidising atmospheres, graphite undergoes oxidation to form carbon dioxide. In bulk form, it is non-flammable but combustible. WebSynthetic graphite is produced from graphitizable carbon forms, i.e., the aforementioned soft carbons, which passed through a mesophase in their thermal history. The basic raw material is the calcined petroleum coke, and 20% coal tar pitch is used as a matrix binder.
