Carbon Black FAQs
What is carbon black?
Carbon black (also called carbon black) is a colloidal particle similar to a sphere formed by incomplete combustion or thermal cracking of hydrocarbon compounds (liquid or gaseous). It exists in the form of aggregates and appears as pure black powder or granular. The particle size, structure and surface activity of products vary greatly depending on raw materials, manufacturing methods and production processes. The main component of carbon black is carbon, and also contains trace amounts of hydrogen, oxygen, ash and moisture.
