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 particle size is between 10 and 100 nm, while the surface particle size is between 20 and 1,500 m 2 /g. Generally speaking, small carbon black particles with a high surface area are darker, have higher viscosity and lower wettability, are harder to disperse, retain greater conductivity and absorb UV radiation well.

The L-isoleucine molecule, C 6 H 13 NO 2, showing features typical of organic compounds. Carbon atoms are in black, hydrogens gray, oxygens red, and nitrogen blue. Although vitalism has been discredited, scientific nomenclature retains the distinction between organic and inorganic compounds.
Total inorganic carbon (C T or TIC) is the sum of the inorganic carbon species. Carbon compounds can be distinguished as either organic or inorganic, and dissolved or particulate, depending on their composition. Organic carbon forms the backbone of key components of organic compounds such as proteins, lipids, carbohydrates, and nucleic acids.
Black carbon is in the air and circulates the globe. Black carbon travels along wind currents from Asian cities and accumulates over the Tibetan Plateau and Himalayan foothills. Black carbon (BC) is the light-absorbing refractory form of elemental carbon remaining after pyrolysis (e.g., charcoal) or produced by incomplete combustion (e.g., soot).
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds — that is, a compound that is not an organic compound. [ 1 ] [ 2 ] The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry .
