Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
Carbon black is a nanostructured material with nearly pure carbon content, generally higher than 95% by elemental composition. It is usually in the form of fine quasi-spherical particles, called “primary particles,” which are connected together by covalent links to form aggregates and agglomerates ( Donnet, 1993 ).
Carbon black, any of a group of intensely black, finely divided forms of amorphous carbon, usually obtained as soot from partial combustion of hydrocarbons, used principally as reinforcing agents in automobile tires and other rubber products but also as extremely black pigments of high hiding power.
Carbon black is a vital component in many everyday products, produced by igniting low-grade petroleum, natural gas, or other types of carbon-based residue, then heating it at high temperatures under a controlled process. What is the History of Carbon Black?
1 Οκτ 2013 · In contrast to CB, there is no universally accepted chemical definition of the term “black carbon”, and it is oftentimes referred to as soot, graphitic carbon, and/or elemental carbon.
26 Ιουν 2024 · Besides rubber reinforcement, carbon black is used as black pigment and as an additive to enhance material performance, including conductivity, viscosity, static charge control and UV protection. This type of carbon black (typically called specialty carbon black) is used in a variety of applications in the coat-
Carbon black is a form of amorphous carbon that has a high surface-area-to-volume ratio. Carbon black is categorized as acetylene black, channel black, furnace black, lampblack, or thermal black, according to its manufacture process.
