Carbon black is one of the darkest and most widely spread materials known. Chemically, carbon black is a colloidal form of elemental carbon consisting of 95 to 99% carbon. Made in specially designed reactors, operating at internal temperatures in the range of 2600° to 3600°F, different grades of Carbon black can be produced with varying aggregate size and structure. It is not the undesired by-product soot, which is known from chimneys or exhausts
Carbon black is an industrial produced raw material with clear defined properties like primary particle size, surface and structure
Carbon black is a high-tech product that can be manufactured reproducible with defined parameters/properties
Carbon black typically contains more than 95% pure carbon with minimal quantities of oxygen, hydrogen and nitrogen
The characteristics of carbon black depend mainly on the manufacturing process/method, and therefore carbon black is classified by the manufacturing process
