1. Harder Than Diamonds
MEEN 3344
By: Eric Fuqua

2. Ultrahard Fullerite (C60):
Estimated hardness of times that of diamonds [1].
Only microscopic quantities now.[1]
Scratch hardness must be measured under Atomic Force Microscope.[1][2]
Under the microscope it is shown that it can scratch diamonds.[2]
Also called buckyballs[2]

3. Carbon Nanotubes: Cylindrical Buckyball formation.[3]
Most composed of fullerite so same hardness, however the intertwining orientation make it difficult to scratch or cut diamonds.[3]
Amazing thermal conductivity
6000 watts per meter per Kelvin (copper-385) [3]
Up to 1000 times the electrical carrying potential of copper [3]
Stiffest and strongest materials discovered on earth[3]
A multi-walled tube has been tested to have a 63GPa tensile strength, which is equal to 6300 kg on a cable with cross-section of 1 mm^2 [3]
Hexagonal Orientation [3]

4. Synthetic Diamonds:
Gem sized diamonds grown 100 times faster than normal Grown using a microwave vapor disposition technique
The by applying 5-7 GPa’s of pressure at an approximated 2000*C, the hardness is said to be raised to 50% higher than that of typical synthetic diamonds.[1]
Regular synthetic diamonds typically have a hardness ranging from
35-75% that of a typical crystal diamond.[5]
