Difference Between Diamond and Graphite

Posted by Sharif Khan on 6th Aug 2018

Diamond and also graphite are chemically the same, both made up of the element carbon, however, they have entirely different atomic and also crystal frameworks. Diamond atoms have a rigid 3 dimensional structure with each atom carefully loaded with each other as well as connected to 4 other carbon atoms.

The factor for the differences in firmness as well as various other physical homes can be explained with the molecular versions listed below.

What is Diamonds?

Diamond is a kind of carbon that takes shape in the crystal system of greatest symmetry referred to as the cubic system born thousands of miles below the surface area of the earth. Diamonds are created after countless years under heat and great pressure. They are brought to the surface area through volcanic eruption. Diamond which are naturally created under the earth crust are referred to as  Rеаl Diаmоndѕ. Man has found out the process of diamond development and also has actually been efficiently produced man-made diamond in laboratory. They are referred to as  ѕуnthеtiс diamonds.

A diamond is an allotrope, or a type, of the aspect carbon (a diamond is really carbon in its most concentrated kind). Within the precious stone, the carbon atoms are arranged in variant of the face-centered cubic crystal structure called a diamond latticework. This arrangement of carbon atoms basically implies that the diamond broadens external at the same rate in all instructions during its initial growth.

Because of its structure, which is extremely inflexible, a diamond could be infected by very few contamination, such as the elements boron or nitrogen. Integrated with its tendency to be clear, this causes the anemic, clear appearance of the majority of diamond. Blue diamonds come from boron pollutants, yellow diamond from nitrogen contamination, brownish diamonds from latticework defects, and environment-friendly diamonds from radiation direct exposure.

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'. , if diamonds are offered really good cut it provides a high degree of brilliancy and a screen of prismatic shades.. 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.

What is Graphite?

Graphite is a non-metal. It iѕ also аn allotropes of саrbоn ѕuсh аѕ diаmоnd and fullеrеnе. It iѕ soft аnd slippery as it iѕ аrrаngеd in lауеrѕ whiсh аrе hеld bу wеаk Vаn der wааlѕ. Every layer iѕ оnlу оnе-аtоm-thiсk.

It саn аlѕо соnduсt еlесtriсitу аѕ every Carbon iѕ only bоndеd tо thrее others, lеаving thе fоurth еlесtrоn free аѕ delocalised еlесtrоn.

Grарhitе iѕ a сrуѕtаllinе fоrm оf carbon, a ѕеmimеtаl, a nаtivе еlеmеnt mineral, and оnе of thе allotropes of carbon. Grарhitе is the most stable form of саrbоn undеr ѕtаndаrd conditions. Thеrеfоrе, it iѕ uѕеd in thеrmосhеmiѕtrу аѕ the standard ѕtаtе fоr defining the heat of fоrmаtiоn оf саrbоn compounds. Grарhitе mау be соnѕidеrеd the highеѕt grаdе оf coal, juѕt above аnthrасitе and alternatively саllеd mеtа-аnthrасitе, аlthоugh it is nоt normally used аѕ fuеl because it iѕ diffiсult tо ignite.

Whаt iѕ the difference between Grарhitе аnd Diаmоnd?

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 120 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.

Diаmоnd аnd graphite саn bе differentiated frоm еасh оthеr in thе following mаnnеr.


  • It is the hardest compound known and also its thickness is 3.5 g/mL.
  • Carbon adhered to four different carbon atoms developing tetrahedron.
  • Tetrahedrons combine to develop 3-D structure.
  • Does not conduct electricity.
  • It does not have any kind of appeal.
  • It has a very high melting factor.
  • The carbon atoms in the structure are sp3 hybridized.


  • It is a soft and also weak substance with density 2.3 g/mL.
  • Each carbon atom is joined to three other carbon atoms by strong covalent bonds to develop level hexagonal rings.

How аrе grарhitе and diаmоndѕ uѕеd?

Uses of Diamond:

  • Diamond is made use of as a gems in jewellery, accessories as well as crowns.
  • Diamond additionally have numerous industrial applications. * Diamonds being very hard is made use of in tools that reduced glass and pierce hard rocks.
  • Diamonds are also utilized as abrasives to cut and also polish other products as well as gems.
  • Diamonds are likewise utilized in blades which are used to execute delicate operations like the cataract operation.
  • Diamonds are utilized in very sensitive thermometers and also windows of room shuttle bus because of its heat delicate homes.
  • Thin diamond membrane layers are utilized to cover the openings in x-ray devices and also lasers.
  • Diamond are also made use of in the manufacture of fine wires, like those utilized in electrical toasters.
  • Diamond is made use of in warmth sinks, which assist conduct the warm far from sensitive components of high performance microelectronics.

Uses of graphite:

  • Graphite in its powdered form is used as a lube in heavy equipment’s.
  • It is also used to make black paint and also inks as a result of its dark, grey color.
  • It is utilized for making lead in pencils.
  • Graphite being an excellent conductor of electrical power is utilized in the manufacture of electrodes, which discovered use in completely dry cells and electric furnaces.
  • Graphite when incorporated with plastic generates a light-weight as well as strong composite product, which is solid Compound Item precede craft components and also Meal Antenna, Tennis Racquet.
  • Graphite crucibles or melting pots are utilized to thaw brass, aluminum as well as many other nonferrous steels.

Diamond and graphite are chemically the same, both made up of the aspect carbon, nevertheless, they have completely different atomic as well as crystal structures. In diamond, the carbon atoms have solid bonds in three measurements, makings it hard. In graphite the bonds create in level layers with carbon atoms having solid bonds on the very same layer with weaker layers above as well as below that makes this graphite weak. Diamond atoms have a rigid three dimensional framework with each atom closely compacted as well as attached to 4 other carbon atoms. Literally diamonds have the tendency to appear shiny and bright (the expensive ones anyhow) as well as graphite had a shabby and also black appearance to it.

Man has actually found out the process of diamond formation and also has actually been successfully produced synthetic diamond in research laboratory. A diamond is an allotrope, or a type, of the component carbon (a diamond is really carbon in its most focused kind)Within a diamond, the carbon atoms are prepared in a variant of the face-centered cubic crystal framework called a ruby latticework.Blue diamond's originated from boron toxins, yellow diamond from nitrogen pollutants, brown diamond from latticework troubles, and environment-friendly diamond from radiation direct exposure.

Both Diamond and Graphite are a crystalline kind of carbon (Both are made of pure carbon).
