Many friends will ask whether carbon black and carbon fiber are allotropes? What are the allotropes of carbon black? Here I will introduce the allotropes of carbon, but the various carbon products mentioned here are pure High single substances, that is, those in high school chemistry textbooks, may not necessarily exist in reality, because impurities will appear in the process of production and processing. Although the purity is very high, it is difficult to achieve 100% purity. Of course carbon black and carbon fiber are allotropes.
The four allotropes of carbon
The four allotropes of carbon are diamond, graphite, amorphous carbon, and C60, among which activated carbon, coke, charcoal, carbon black, and glassy carbon are the main forms of amorphous carbon. Carbon nanotubes, discovered in 1991, should also be allotropes of carbon. It can be seen that activated carbon is an allotrope of carbon, carbon fiber and graphite are allotropes, carbon fiber and diamond are allotropes, and carbon black and carbon fibers are also allotropes.
Are carbon black and carbon fiber a single substance of carbon?
Carbon black generally refers to simple carbon particles, so carbon black is a simple substance of carbon, and carbon fiber is a high polymer, so it must not be a simple substance, but it cannot be regarded as a compound. Simple substances and compounds are concepts of inorganic chemistry, while carbon fibers belong to organic chemistry. and polymer chemistry.
Is carbon black carbon fiber isomers?
Isomers refer to isomers, which are compounds with the same molecular formula but different arrangements of atoms, and allotropes refer to compounds composed of the same single chemical element, which have different properties due to different arrangements of simple substance. It can be seen that carbon black and carbon fiber are not isomers, but allotropes.
