Charcoal is a highly porous form of carbon obtained by heating wood or other organic materials in the absence of air. It is commonly produced by slow pyrolysis or destructive distillation, where the organic matter is heated to high temperatures (typically between 600-900 degrees Celsius) in the absence of oxygen. This process eliminates the volatile components from the material, leaving behind a residue of almost pure carbon.
The resulting charcoal is lightweight, black in color, and has a rough texture due to its numerous pores. Its high porosity enables it to absorb gases, liquids, and impurities, which makes it a versatile material with various applications. Charcoal is commonly used as a fuel source due to its high energy density and low smoke production. It is widely utilized in industry, including in metallurgy, chemical production, and as a reducing agent in the creation of iron and steel.
In addition to its use as a fuel, charcoal is also employed in various domestic settings. It is commonly used as a cooking and heating fuel, both in traditional stoves and modern BBQ grills. Charcoal also finds application in art, where it is used as a drawing medium due to its ability to create rich, dark lines. Furthermore, activated charcoal, a form of charcoal that has been processed to increase its adsorption capacity, is widely used in medicine, where it serves as a treatment for poisoning and overdoses.
