How is diamond different from graphite

Diamond have a hardness far surpassing compared to that of any other substance understood to us. It has a very high level of openness and dispersion or 'fire'. As a result of its hardness a lot of the diamonds which are mined are made use of for industrial objective as well as few are taken right into gems. Graphite is a non-metal. Both Diamond and also Graphite are a crystalline kind of carbon Both are made of pure carbon. They are the same in the chemical structure, they vary a whole lot in the physical make-up.

On the Moh s array, Diamond rates as 10 making it the hardest mineral as compared to Graphite, which is the softest. Thus, based upon the physical buildings, they are utilized for various functions. Also, as a result of the rarity, a Diamond is far more expensive than Graphite.

Although they are made from the exact same component Carbon , a Diamond differs from Graphite in the atomic structure. In Diamonds, the atoms are carefully packed with together with each atom connected to various other carbon atoms as compared to Graphite where the bonds in between the layers are weak. This is the reason why Diamonds have a extremely solid as well as inflexible framework. Both are pure carbon, however vary in crystalline framework because they are adhered differently. A carbon atom has 4 electrons that are unpaired as well as can develop bonds by pairing with electrons from various other atoms.

When it comes to diamond and graphite we are speaking about just various other atoms of carbon. In Diamond, all of the electrons are matched an covalent bonds to other carbon atoms. The diamond framework is hard to envision in 3 dimensional room, however very easy to see in a 3 dimensional version.

In Graphite, 3 of the 4 electrons remain in covalent bonds With 3 bonds at degrees from each different other one could make a level framework. Graphite forms flat sheets. Graphite is a lot less thick compared to diamond due to the fact that of the space between the layers. Diamond and graphite are both large covalent materials made totally of carbon atoms. Both have chemical formula, yet they do not have a molecular formula.

Diamond : Extremely hard. Uses of Diamond:. Uses of graphite:. This means that when the layers or sheets are rolled up into fibers, and those fibers are twisted into threads, the true strength of the bonds becomes apparent. The threads are molded into shape and held in place by a binder such as an epoxy resin. The resulting composites have some of the highest strength-to-weight ratios of any materials.

The differences between diamond and graphite highlight the importance of crystal structure to the properties of a gemstone. For example, all gems that have a cubic crystal habit, where the crystal structure is completely symmetrical, have an important property in common. Cubic solids refract light in all directions at the same velocity. So even though diamond, garnet and spinel have quite different chemical compositions, they are all singly refractive because of their similar crystal structure.

Other less symmetrical crystal groups are doubly refractive , including orthorhombic, monoclinic and triclinic, all of which have specific internal symmetries and axes that dictate how light bends as it enters the crystal. Dimensions are given as; length x width x depth , except for round stones which are; diameter x depth.

You may think Graphite is soft because it is used in pencils but the layers themselves are actually very strong, however because each carbon only has three bonds, the layers have delocalised 'free' electrons between them.

These electrons act as lubricant between layers, allowing them to slide over one another, making graphite appear soft.

The free electrons also mean that Graphite conducts electricity. Diamond does not have these free electrons so does not conduct electricity. How can Diamond and Graphite both be made of carbon but be so different?
