Description
A fine particle carbon pigment obtained as soot from the incomplete combustion of many different types of organic materials, such as fruit pits, vine stalks, husks, bone, ivory, cork, resins, natural gas, or oil. Carbon black pigments have been used since ancient times. The carbon is collected as the charcoal residue, or in the case of Lampblack, as the smoke residue. Carbon black is usually a fine, soft, black powder, but some blacks contain mineral impurities and tarry hydrocarbons that give it a bluish, reddish or brownish tinge. It is very stable and unaffected by light, acids and alkalis. It absorbs ultraviolet radiation and has very good hiding properties. Carbon black has poor drying properties in oil paints, but is commonly used in printing and lithograph inks and in Chinese ink sticks. In industry, carbon black is used as a filtration material and a filler/pigment in coatings, rubber, plastics, paints, carbon paper, and crayons. As a filler, carbon black increases resistance to abrasion and adds electrical conductivity. About one fourth of the weight of a standard automobile tire is carbon black.
See also Animal black, Charcoal black.
Synonyms and Related Terms
Pigment Black 6 and 7; CI 77266; Kohlenstoffschwarz (Deut.); negro orgánico (Esp.); mayro toy anthraka (Gr.); hiilimusta (Fin.); nero di carbone (It.); noir de carbone (Fr.); sumi (Jap.); koolstofzwart (Ned.); negro de carvão (Port.); channel black
Examples include: lampblack; gas black; diamond black; smoke black; soot black; flame black; furnace black; acetylene black; thermal black; graphite; charcoal black; coal black; bone black; vine black
Risks
Once considered carcinogenic because of impurities, however, new manufacturing techniques have eliminated contamination. Chronic inhalation may cause respiratory irritation. Combustible. Burning may form toxic carbon monoxide gas.
Birla Carbon: SDS
Physical and Chemical Properties
