Carbon is a very versatile element that can form numerous useful allotropes. In addition to graphite, which is used in pencils and other writing implements, it also exists as diamonds and fullerenes. The allotropes exhibit different physical properties and chemical structures but share the same atomic arrangement. carbon powder is an example of one type of carbon material with a variety of uses in the industrial and scientific arenas.
Activated carbon, also known as activated charcoal, is a fine powdered substance made from coal or other raw materials and processed to have small pores that increase the surface area for adsorption and reaction. Activated carbon is often used to filter contaminants from water and air.
Powder Activated Carbon (PAC) is an activated carbon product with a particle size distribution predominantly below 0.075mm US mesh, produced by milling or pulverising activated carbon. PAC is widely used in seasonal applications such as taste and odour control for drinking water, and is an ideal choice for purification of industrial effluents.
The Molasses Number of a particular activated carbon is an indication of the potential pore volume available for adsorption of color bodies in a waste water application. However, the molasses number is not a complete measure of the effectiveness of an activated carbon in a specific waste water treatment application, because pore size is only a part of the overall adsorption mechanism.
Carbon black can be produced as a fine powder or in a number of other forms including rod, ingot, pellets, disc, granules and wire. The surface chemistry of a particular carbon black is important to its performance in rubber applications as it affects pigment wetting, dispersion and curing characteristics in selected systems.
