What is carbon black give one use of it?
carbon black, any of a group of intensely black, finely divided forms of amorphous carbon, usually obtained as soot from partial combustion of hydrocarbons, used principally as reinforcing agents in automobile tires and other rubber products but also as extremely black pigments of high hiding power in printing ink.
What is structure of carbon black?
STRUCTURE. This is a measure of the three-dimensional fusion of carbon black particles to form aggregates, which may contain a large number of particles. Increasing carbon black structure increases modulus, hardness, electrical conductivity, and improves dispersibility of carbon black, but increases compound viscosity.
How many types of carbon black are there?
1 CB. CB is produced by incomplete combustion of hydrocarbons and is a conventional reinforcing, conductive or coloring filler in rubber compounds. Different types of CBs are thermal black, furnace black, lamp black, channel black, and acetylene black.
Why is carbon black called carbon?
However, carbon black is widely used as a model compound for diesel soot for diesel oxidation experiments. Carbon black is mainly used as a reinforcing filler in tires and other rubber products….Carbon black.

What is carbon black process?
Carbon black is produced by the reaction of a hydrocarbon fuel such as oil or gas with a limited supply of combustion air at temperatures of 1320 to 1540°C (2400 to 2800°F). The unburned carbon is collected as an extremely fine black fluffy particle, 10 to 500 nanometers (nm) in diameter.
What is SRF carbon black?
REGAL® SRF carbon black is a pelleted carbon black in the class known as Semi- Reinforcing Furnace (SRF) carbon blacks and conforms to ASTM N772 carbon black target values. REGAL® SRF carbon black has a lower surface area than ASTM N500 and N600 carbon blacks and a structure lower than ASTM N774 carbon black.
What is the pH of carbon black?
3.1
3.1 The pH level of a carbon black is known to affect the vulcanization of some rubber compounds.
What is carbon black powder?
Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. Carbon black is mainly used as a reinforcing filler in tires and other rubber products. In plastics, paints, and inks, carbon black is used as a color pigment.
What is the difference between carbon black and activated carbon?
The key difference between carbon black and activated carbon is that the surface-area-to-volume ratio of carbon black is lower than that of activated carbon. Besides, carbon black is produced from incomplete combustion of heavy petroleum products while activated carbon is produced from charcoal.
What Colour is carbon black?
Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
What is BMW carbon black?
Carbon Black looks blue next to a BSM car. On its own, CB is very dark/black looking in darker light and in full sun/highlights the navy / dark blue comes out. It can almost be a violet blue depending on the light.
