Differbetween
Diamond, graphite and fullerene are allotropes of carbon. In summary, the key difference between diamond graphite and fullerene is that diamond has a diamond cubic crystal structure and graphite has a hexagonal crystal structure, while fullerene occurs as a large spheroidal molecule.

What is the difference between diamond and graphite?
Diamond is one of the hardest materials known, is transparent to light, and does not conduct electricity at all. Graphite is soft, gray, and can conduct electricity reasonably well. Such different properties, from two substances that are composed of exactly the same kinds of atoms!
Is graphite a fullerene?
Cylindrical fullerenes are also called carbon nanotubes or buckytubes. ... The discovery of fullerenes greatly expanded the number of known allotropes of carbon, which had previously been limited to graphite, diamond, and amorphous carbon such as soot and charcoal.
Is Diamond harder than fullerene?
Blank obtained a new material based on fullerenes—ultrahard fullerite, or 'tisnumit. ' According to the measurements, this new material could scratch diamond—it was, in fact, harder than diamond." The substance was not single-crystal material; it contained amorphous carbon and 3-D-polymerized molecules of C60.

Why is diamond more expensive than graphite?
Diamond is costlier due to the rareness, unique properties and wide varieties of application potentials than graphite. ... Chemists have figured out that under the right combination of temperature, pressure and time, carbon atoms e.g. from graphite can be converted into diamonds. An expensive process.
Which is harder diamond or graphite?
However, diamond is harder than graphite because of the carbon atoms in a diamond form 4 covalent bonds in the form of tetrahedral structure. While the carbon atoms in the graphite form 4 covalent bonds in the form of hexagonal structure. ... This is the reason why diamond is harder than graphite.
Can a diamond conduct electricity?
Diamonds do not conduct electricity.
Many engineers once believed diamonds could not conduct electricity due to a tetrahedron structure made by covalent bonds between carbon atoms, which doesn't allow for free electrons to carry current.
Why is diamond so hard?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
Is C60 a diamond?
At high temperatures above 1500 °C, C60 crystals are transformed into diamond in a pressure range of 9–15 GPa [5]. ... Our recent work has shown that C60 can be converted into diamond under the same SPS conditions as carbon nanotubes are converted to diamond (1500 °C, 80 MPa) [12].
Why does diamond not conduct electricity but is very strong?
Diamond is very hard due to the strong covalent bonds and rigid tetrahedral 3d arrangement. It does not conduct electricity, as there are no electrons free to move and carry charge. ... Carbon atoms have four unpaired electrons and can form four covalent bonds.
Can fullerenes conduct electricity?
All fullerenes have a structure similar to graphite in that each carbon atom forms single covalent bonds with three neighbouring carbon atoms. This forms a hexagonal plane structure, which can be bent to form different fullerenes. ... These can move throughout the fullerene, allowing conduction of electricity.
Why are fullerenes soft and slippery?
Its molecules are made up of 60 carbon atoms joined together by strong covalent bonds. ... There are weak intermolecular forces between molecules of buckminsterfullerene. These need little energy to overcome, so buckminsterfullerene is slippery and has a low melting point.
