What is the difference between granite and graphite?

Answer 1

Granite is a stone covering

graphite is a lubrecant

Answer 2

Graphite as with diamond, is one of the allotrope's of carbon. However, unlike diamond, graphite is an electrical conductor and a semi-metal.

It is also considered the most stable form of carbon under 'standard conditions', therefore, it is often used in thermo-chemistry as the standard for defining the heat of formation of carbon compounds.

Answer 3

Graphite is made up of sheets of sp2 bonded carbons in a 2d array each each carbon is bonded to only 3 other carbons so the individual sheets arent chemically bonded to one another, the sheets are held together by weak dispersion forces. Because of this the sheets can easily slip past one another or be broken apart resulting in a pretty soft material. Diamond on the other hand is sp3 bonded in a tetrahedral 3d array, each carbon is bonded to 4 other carbons covalently in a 3d structure and they cannot slide past one another, they are very tightly held in that arrangement. The arrangement of the carbon atoms in diamond is what gives it its hardness, clarity, density and other properties.

Answer 4

They are both pure carbon, (charcoal isn't actually, its refined state graphite is). The only difference is the structure of the carbon atoms, while graphite has a cubical/rectangular prism arrangement (which result in weak structure AKA flaking) however a diamond's atomic structure is octahedral, which is incredibly strong.

Answer 5

They have totally different crystal structures: diamond forms a 3D face-centered cubic crystal that tightly interlocks the atoms together making it extremely hard, graphite forms a 2D hexagonal crystal of flat sheets that are not attached to each other and thus readily slide making it very soft and fragile (as well as a very effective lubricant).

Answer 6

Both are allotropes of carbon. They are different because of their molecular structure.

Answer 7

Diamond and graphite are both allotropes of the base element carbon, and each with different molecular patterns.

Answer 8

Diamond and graphite hasn't the same properties.
