Carbon Black is defined
as any of the various finely divided forms of carbon
derived from the incomplete combustion of natural
gas or petroleum oil. Carbon black is produced through
controlled, incomplete combustion of hydrocarbons |
|
|
Carbon Black is actually
elemental carbon in the form of extremely fine particles
having an amorphous molecular structure |
|
|
Carbon Black is also
known as acetylene black, channel black, furnace
black, lamp black, lampblack, thermal black, and
noir de carbone |
|
|
In the olden times, the
Chinese used Carbon Black produced from resins and
vegetable oils in inks and water colours. The Greeks
and Romans used Carbon Black to paint the walls
of their buildings |
|
|
Today, Carbon Black is
used in almost every part of the car, from the engine
compartment to the tyres and the exterior coatings.
It is also used to reinforce rubber. Carbon Black's
biggest application is as a reinforcing filler in
rubber products |
|
|
Carbon Black is used
as inks in copiers and computer printer cartridges
and paints. It is also an ingredient in crayons
and polishes |
|
|
Manipulation of Carbon
Black surface can enhance the physical properties
of rubber. Almost all rubber products, especially
those that need to have abrasion wear properties,
use Carbon Black. Hence, they are black in colour |
|
|
Carbon Black has chemisorbed
oxygen complexes (carboxylic, quinonic, lactonic,
phenolic groups and others) on the surface. These
surface oxygen groups are referred to as volatile
content |
|
|
The D24 ASTM Committee
on Carbon Black instituted the nomenclature for
rubber grade carbon blacks in 1968. The nomenclature
consists of a prefix letter followed by a three-digit
number. The prefix, either N or S indicates whether
the grade is Normal or Slow curing material |
|
|
The D24 ASTM Committee
assigns the second and third digits to new products
as the various manufacturers develop them. In general,
lower structure blacks have been assigned lower
numbers and higher structure blacks, higher numbers |

A normal car tyre contains
about 3.63 kg of Carbon Black |
