Black Carbon

What is Black Carbon?

Black carbon (BC) is a particulate matter left after the incomplete combustion of fossil fuels and biomass. It is mainly pure carbon with charcoal and ash as its main components.

Black carbon is a climate forcing agent that contributes to global warming. It is highly toxic and can penetrate the lungs, affecting the cardiovascular system, and even cause death.

What are the Uses of Black Carbon?

Black carbon is highly rust-proof and is used in long-distance oil and gas pipelines.

How is it Different from Carbon Black?

Carbon black (CB), also known as lampblack, is a form of carbon produced commercially by burning fossil fuels, biofuels, and biomass under a limited supply of air.

Uses of carbon black

  • Carbon black is used in magnetic tapes and semiconductors due to its high conductivity.
  • Its property of high pigmentation makes it suitable for use in jet inks and eye mascaras, but its presence in eye mascaras can cause cancer. Additionally, it is also used as a pigment in adhesives and paints.
  • It is used as a rubber reinforcing additive in several rubber products. Its use in tires protects them from the harmful effects of UV rays and ozone.

What is Soot?

Soot is the unwanted product left after the incomplete burning of fossil fuels and biomass. Black carbon is a part of soot and imparts the black color to it. Soot is a primary pollutant that causes smog.
