CAS number： 99685-96-8
Molecular formula： C60
molecular weight： 720.64
Chemical structure：
Fullerene C60 has a special spherical configuration, and is the best round of all the molecules. Because of the structure, all molecules of C60 have special stability, while a single C60 molecule is extremely hard at the molecular level, which makes C60 possibly as core material of lubricant; C60 is so hopefully to translate into a new abrasive material with high hardness as a result of C60 molecules’ special shape and strong ability to resist external pressures.
Fullerene-C60 is a non-toxic antioxidant 100–1000 times more active than vitamin E.
