| Description: | Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, and a small amount from vegetable oil. Its physical appearance is that of a black, finely divided pellet or powder. Carbon black consists of more than 96 percent of amorphous carbon and of small quantities of oxygen, hydrogen, nitrogen, and sulfur. Most of these elements are concentrated on the surface. Subsequently oxidized carbon black may contain up to 15 percent of oxygen. Carbon black can be tailored to the respective intended purposes, hence is characterized by a high diversity that is essentially determined by the method of production and the variation of the process parameters. Carbon black consists of chain-type or botryoidal aggregates that have coalesced during production from smallest, mostly spherical particles.While still in the reactor, these aggregates form large agglomerates. The types of carbon black that have a high specific surface and widely ramified aggregates are particularly conductive. These conductive carbon blacks are used, for example, in antistatic finishings of plastics. For many applications, the carbon blacks are subjected to aftertreatments. In paints and varnishes with high color intensities, one uses e.g. carbon blacks that have been enhanced through subsequent oxidation. | |
