Carbon black is in powder or pellet form and is insoluble in water and in organic solvent.
Carbon black is largely used as reinforcement in automobile tyre and non-tyre applications (primarily mechanical rubber goods).
Among the most important parameters that determine the performance of carbon black are surface area and structure. In general, a high surface area results in high reinforcement, particularly good tensile and tear strength and good abrasion resistance.

The main route for carbon black manufacture is by the partial oxidation of vapourised heavy oil fractions in an oil furnace. The most desirable feedstock is low in sulphur and high in aromatics and usually comes from the bottom of the refinery barrel. The product, sometimes called furnace black, is a finely divided form of carbon with a very high surface area.
Carbon black has also been made from natural gas by partial combustion or thermal cracking.
