  1. MATERIAL SCIENCE Diamond

  2. PROPERTIES • Transparent crystal of tetrahedrally bonded carbon atoms and crystallizes into the face centered cubic diamond lattice structure. • Most notable are its extreme hardness, • High dispersion index • Extremely high thermal conductivity (900 – 2320 W/m K) • Melting point of 3820 K (3547 °C / 6420 °F) • Boiling point of 5100 K (4827 °C / 8720 °F). • Density ranging from 3.15 to 3.53 g/cm³, with very pure diamond typically extremely close to 3.52 g/cm³.

  3. Properties • Hardness: Diamond is the hardest natural material known to man: It has a hardness of 10 (hardest) on Mohs scale of mineral hardness • Electrical conductivity: Use as semiconductors • Toughness: The toughness of natural diamond has been measured as 3.4 MN m-3/2,which is good compared to other gemstones, but poor compared to most engineering materials. • Color: Diamonds can occur in nearly any color, though yellow and brown are by far the most common

  4. APPLICATIONS INDUSTRIAL APPLICATIONS • Employed in drill tips and saw blades • Precision Instruments • Ground into a powder for use in grinding and polishing applications. • Use in specialized windows

  5. APPLICATIONS OTHER APPLICATIONS • Jewelry • Use in laboratories for high pressure experiments • High Performance bearings FUTURE APPLICATIONS • Use as a semiconductor to build microchips from or use as a heat sink in electronics. • Super electronics • Indomitable optical windows, • Unscratchable surfaces - maybe the next watch bezel - diamond is an obvious choice.
