Carbon diamond vs gerahpit

  1. 1. Diamond Vs Graphite<br />Done by: Damien Poh<br />
  2. 2. Diamonds<br />Diamond is the hardest natural material.<br />On the Mohs scale of hardness, diamond is a 10. Which has an absolute hardness of 1600.<br />Unable to conduct electricity.<br />Usually transparent<br />
  3. 3. Graphite<br />Unlike diamond, graphite is a conductor, and can be used, for instance, as the material in the electrodes of an electrical arc lamp. <br />Graphite is also soft unlike diamonds.<br />Usually opaque.<br />
  4. 4. Properties<br />Diamonds<br />Atomic density [cm-3] : 1.77 x10 23<br />Thermal conductivity : 25<br />Melting point : 4500<br />Bond length : 1.545<br />
  5. 5. Properties<br />Graphite<br />Atomic density [cm-3] :1.14 x10 23<br />Thermal conductivity : 30 0.06<br />Melting point : 4200 <br />Bond length : 1.1421<br />
  6. 6. Why???<br />Why does diamond insulate electricity while graphite conduct electricity even though both are made of carbon?<br />
  7. 7. Explanation :<br />Graphite and diamond are both made from carbon, which has 4 electrons in it's outer shell. Diamond has four bonds, meaning there are no free electrons. Graphite has three bonds giving it a free electron which alows the current of electricity to flow. <br />
  8. 8. Why???<br />Why is diamond hard and graphite soft when both are made of carbon?<br />
  9. 9. Explanation :<br />The answer lies in the way the carbon atoms form bonds with each other. <br />
  10. 10. Explanation :<br />While there are strong covalent bonds between carbon atoms in each layer, there are only weak forces between layers. This allows layers of carbon to slide over each other in graphite. That is why graphite is soft..<br />
  11. 11. Explanation:<br />Each diamond atom is the same distance to each of its neighboring carbon atoms. There is a rigid network of bonds within the diamond crystal<br />
