  • Synthetic graphite is a material consisting of graphitic carbon which has been obtained by graphitizing of non-graphitic carbon, by CVD (chemical vapor deposition) from hydrocarbons at temperatures above 2500 K, by decomposition of thermally unstable carbides or by crystallizing from metal melts supersaturated with carbon. (wikipedia.org)
Vapor2
  • C2 is a component of carbon vapor. (wikipedia.org)
  • One paper estimates that carbon vapor is around 28% diatomic, but theoretically this depends on the temperature and pressure. (wikipedia.org)
Diatomic3
  • Diatomic carbon (systematically named dicarbon and 1λ2,2λ2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C2] or C2). (wikipedia.org)
  • The light of gas rich comets mainly originates from the emission of diatomic carbon. (wikipedia.org)
  • An example is C/2014 Q2 (Lovejoy), where there are several lines of C2 light, mostly in the visible spectrum , forming the Swan bands.C/2022 E3 (ZTF), visible in early 2023, also exhibits green color due to the presence of diatomic carbon. (wikipedia.org)
