BLACK CHARCOAL

In terms of properties, black carbon consists solely of carbon atoms, appears as a black powder, and is insoluble in water. The molar mass of black carbon is 12 g/mol. All types of black carbon have oxygenated surface complexes that are chemically adsorbed. Examples include carboxylic, quinonic, and lactonic complexes. These complexes are present on the surface of the black carbon particles. Depending on the conditions and production steps, the extent of these surface complexes can vary across particles. These surface compounds are considered volatile. Due to the volatility of these complexes, black carbon powder is a non-conductive material.

Black carbon has numerous applications. It is primarily an important reinforcing material. It is used as a reinforcing filler in tires and other rubber products. Additionally, it is used as a pigment in paints, plastics, inks, and more. Plant-derived black carbon is also useful as a food colorant.
