Aggregated Diamond Nanorods
ADNRs, are an allotrope of carbon believed to be the hardest and least compressible known material, as measured by its isothermal bulk modulus; aggregated diamond nanorods have a modulus of 491 gigapascals (GPa), while a conventional diamond has a modulus of 442 GPa. ADNRs are also 0.3% denser than regular diamond.
The ADNR material is also harder than type IIa diamonds and ultrahard fullerite.
A process to produce the substance was discovered by physicists in Germany, led by Natalia Dubrovinskaia, at the University of Bayreuth in 2005.
ADNRs are made by compressing allotropic carbon fullerene molecules (generally 60 carbon atoms per molecule) to a pressure of 20 GPa, while at the same time heating to 2500 Kelvin, using a unique 5000 metric tonne multi anvil press. The resulting substance is a series of interconnected diamond nanorods, with diameters of between 5 and 20 nanometres and lengths of around 1 micrometre each.
They have used diamonds to cut steel.

Is it fact or opinion that diamonds are the hardest substance on earth?
This is a fact. It can be verified by way of experimentation, and is true regardless of what anyone believes or disbelieves.
Which is the second hardest substance after diamond on earth?
The second hardest substance after diamond on earth is cubic boron nitride. It is often used as an abrasive and cutting tool material due to its exceptional hardness and thermal conductivity.
Hardest known substance?
Diamond is the hardest known natural substance, with a score of 10 on the Mohs scale of mineral hardness. It is made up of carbon atoms arranged in a crystal lattice structure, giving it its exceptional hardness and durability.
What is the name of the hardest solid?
The name of the hardest solid is a diamond; it is the hardest object known to humankind.
Is graphene is hardest thing in the world?
Graphene is not the hardest material in the world; it is actually one of the strongest and lightest materials known. Graphene's strength comes from its unique structure, where carbon atoms are arranged in a single layer. While graphene has impressive strength-to-weight ratio, there are harder materials like diamond or aggregated diamond nanorods.
