Carbon Black Uses and Applications 

Carbon black is a name used to describe a variety of very black, finely split forms of amorphous carbon that are employed as reinforcing agents in vehicle tires and other rubber goods, as well as extremely dark pigments with excellent hiding power in printing ink, paint, and carbon paper. Carbon black is also employed in electrical circuits in the form of protective coatings, polymers, and resistors. As a reinforcing filler, it considerably improves wear and abrasion resistance. Carbon black makes up around a quarter of the weight of a normal automotive tire. Even more carbon black is applied to tires on vehicles that must prevent building up an electrostatic charge, such as oil trucks and hospital operating carts, to make the rubber electrically conductive.

Carbon Black Structure and Production

Carbon black particles have a spherical shape and are less crystalline than graphite. Carbon black converts into graphite when heated to 3,000° C for a lengthy period of time. Carbon blacks are one of the most finely separated materials on the market, with particle sizes changing widely depending on the manufacturing technique. When smoky flames from small jets collide with iron channels, channel or impingement black is generated, which is scraped off by passing the channels through stationary scrapers.Incomplete combustion of a range of gaseous or liquid hydrocarbons in refractory chambers produces furnace blacks.
When hydrocarbons are degraded by contact with hot refractories in the absence of air, thermal blacks are formed. Lampblack, the earliest known black pigment, is made by heating oil, generally coal-tar creosote, in shallow pans in a furnace with a controlled ventilation to generate a thick cloud of smoke. The breakdown of acetylene gas warmed to 800° C in refractory chambers in the absence of air produces acetylene black. It’s employed in applications like dry cells that require a lot of electrical conductivity.
