What Is Carbon Black?

What is carbon black? A vital component in making many of the products we use every day stronger, deeper in color and longer lasting, carbon black in its pure form is a fine black powder, essentially composed of elemental carbon. It is produced by partial burning and pyrolysis of low-value oil residues at high temperatures under controlled process conditions.

Carbon black is mainly used to strengthen rubber in tires, but can also act as a pigment, UV stabilizer, and conductive or insulating agent in a variety of rubber, plastic, ink and coating applications. Apart from tires, other everyday uses of carbon black include hoses, conveyor belts, plastics, printing inks and automotive coatings.

The fundamental properties of carbon black determine application performance. These include:

  • Particle Size
  • Structure
  • Porosity
  • Surface Chemistry or Surface Activity
  • Physical Form


At Birla Carbon, we produce carbon black in a high temperature reactor through a tightly controlled flame-synthesis process that uses oil, and sometimes natural gas, as feedstock. The oil is usually a residue derived from crude oils or coal and is purchased from refineries, petrochemical plants and coal tar distillers.

By making adjustments to the reactor conditions – such as temperature, flow rates, reaction time and reactor design – we are able to produce a wide variety of carbon black grades with different morphology (specific surface area and structure level) to meet the diverse needs of all of our customers. Throughout the manufacturing process, we use distributive control systems to ensure our products meet the highest quality standards.

The six-step carbon black manufacturing process produces large quantities of hot reactor tail gas with a heating value that can be utilized to make steam and electricity. We recover as much as possible of this tail gas energy for our own internal energy needs, but we also supply our energy surplus to businesses and homes around our sites. This greatly reduces our net greenhouse gas emissions and provides a valuable resource to our neighboring communities and partners.
