What is carbon black?

Carbon black is finely divided carbon produced by incomplete combustion of methane or other hydrocarbon gases (by letting the flame impinge on a cool surface). This forms a very fine pigment containing up to 95 percent carbon, which gives a very intense black color that is widely used in paints, inks, and protective coatings, and as a colorant for paper and plastics. It is also used in large amounts by the tire industry in the production of vulcanized rubber.
