Carbon Black

Carbon Black About carbon black Carbon black [C.A.S. NO. 1333-86-4] is virtually pure elemental carbon in the form of colloidal particles that are produced by incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons under controlled conditions. Its physical appearance is that of a black, finely divided pellet or powder. Its use in tires, rubber and plastic products, printing inks and coatings is related to properties of specific surface area, particle size and structure, conductivity and color. Carbon black is also in the top 50 industrial chemicals manufactured worldwide, based on annual tonnage. Carbon blacks are a group of intensely black submicron size pigments, composed of essentially pure carbon and made by the darkest and most finely divided materials known. Chemically, carbon black composition of hydrocarbons in an open diffusion flame, in a partial combustion chamber, or in a thermal decomposition chamber in absence of air.
