Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is virtually a pure form of elemental carbon manufactured through incomplete combustion of hydrocarbons such as FCC tar, coal tar, or ethylene cracking tar, and contains more than 95% pure carbon, other components are oxygen, hydrogen and nitrogen. The black particles are 10nm to approximately 500nm big and fuse into chain-like aggregates, which define the structure of individual Carbon Black grades. Depending on the production process Carbon Black types differ in size, surface chemistry, porosity and many other characteristics. During the after-treatment process the oxygen percentage within the Carbon Black can be changed according to the required needs. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content. Carbon Black grades are determined by industry-wide standards which have been developed by the German Institute for Standardization (DIN), the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM), whereas ASTM widely used, especially for Rubber Carbon Black grades.
