Bone char (Latin: carbo animalis) is a porous, black, granular material produced by charring animal bones. Its composition varies depending on how it is made; however, it consists mainly of tricalcium phosphate (or hydroxyapatite ) 57–80%, calcium carbonate 6–10% and carbon 7–10%. [ 1 ]
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln , the heat is supplied by burning part of the ...
The word "biochar" is a late 20th century English neologism derived from the Greek word βίος, bios, "life" and "char" (charcoal produced by carbonization of biomass). [8] It is recognized as charcoal that participates in biological processes found in soil, aquatic habitats and in animal digestive systems. [citation needed]
Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area [1] [2] available for adsorption or chemical reactions. [3]
Charcoal is a blackish residue of impure carbon obtained by heating animal and vegetable substances.

A series of processes that involve carbonization. [2]Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization.
An example of fusain, charcoal that has been fossilized, found at a spoil pile from an underground coal mine in Grundy County, Illinois, US. Fusain is a fossilised carbon deposit which, after some controversy, has been identified as fossilised charcoal. [1] It is fibrous, black and opaque, and often preserves details of cell wall architecture.
