The Difference Between Carbon Black And Graphite



Natural graphite is a crystal, and carbon black is unshaped. Compared with chemical properties, carbon black is more active, and carbon black absorbs impurities more strongly.

 

Carbon black, also known as carbon black, is an amorphous carbon. Light, loose and very fine black powder with a very large surface area ranging from 10 to 3000 m2/g. It is a carbonaceous material (coal, natural gas, heavy oil, fuel oil, etc.) that is incompletely burned or decomposed by heat in the absence of air. The product obtained. The proportion is 1.8-2.1. It is called "gas black" made of natural gas, "light black" made of oil, and "acetylene black" made of acetylene. In addition, there are "slot black" and "furnace black". According to the performance of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wearing carbon black" and the like. It can be used as a black dye for the manufacture of Chinese inks, inks, paints, etc. It is also used as a reinforcing agent for rubber.


Graphite is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms (multiple hexagons arranged in a honeycomb shape) to form a covalent molecule by covalent bonding. [1] Since each carbon atom emits an electron, those electrons are free to move, so graphite is an electrical conductor. Graphite is one of the softest minerals and its use includes the manufacture of pencil leads and lubricants. Carbon is a non-metallic element located in Group IVA of the second cycle of the Periodic Table of the Elements. Latin is Carbonium, meaning "coal, charcoal", and the Chinese character "carbon" is composed of charcoal "char" and stone characters, from the word "char".
