Carbon Black

Description

　　Carbon black is a fine powder produced by incomplete combustion of a carbonaceous material(pertroleum or coal tar).Its compositionis mainly carbon element,and contains a small amount of oxygen, hydrogen and sulfur.It is a pure black particle or powder,which is nearly pherical,insoluble in water,acid and alkali.and can be burned in the air to become carbon dioxide.
