Ultrahard fullerite (C60) is a form of Carbon found to be harder than Diamond , and which can be used to create even harder materials, such as Aggregated Diamond Nanorods . Specifically, it is a unique version of . In turn, using more accurate measurements, these values are now known for diamond hardness. A Type IIa Diamond (111) has a hardness value of 167±6 Gigapascal s (GPa) when scratched with an ultrahard fullerite tip. A Type IIa diamond (111) has a hardness value of 231±5 GPa when scratched with a diamond tip; this leads to hypothetically inflated values. Ultrahard fullerite has a hardness value of 310 GPa, though the actual value may range ±40 GPa, since testing done using an ultrahard fullerite tip on ultrahard fullerite will lead to, like diamond on diamond, distorted values. It is thought that Beta Carbon Nitride will have a hardness value, if harder than diamond, less than that of ultrahard fullerite. C60 has also been used to create an even harder material: Aggregated Diamond Nanorods {Link without Title} |
