The hardest substance known is Lonsdaleite. The reason it is so strong is because it has a hexagonal unit cell, related to the diamond unit cell in the same way that the hexagonal and cubic close packed crystal systems are related. The 'diamond' structure can be considered to be made up of interlocking rings of six carbon atoms, in the chair conformation. In lonsdaleite, some of the rings are in the boat conformation instead.
Lonsdaleite is simulated to be 58% harder than diamond and to resist indentation pressures of 152 GPa, whereas diamond would break at 97 GPa. Lonsdaleite is found in nature inside of meteorites that were made of graphite became superheated as it entered the Earth's atmosphere and then slammed into the ground with a great enough pressure to force the atoms into a hexagonal structure.
I thought it was carbon nanotubes or carbon nanorods.
The hardest known naturally occurring material is diamond, which is composed of carbon atoms arranged in a strong, rigid crystal structure. However, scientists have also created synthetic materials that are harder than diamond, such as aggregated diamond nanorods.
The simple answer is.... a solid. Molecules of a solid are already packed very close together, with little room to move around, which is why a solid is, for lack of a better word, solid. The molecules of a liquid, however, have enough space between them to flow around each other, giving them a little room to compress. A gas is by far the easiest to compress. Gas molecules have so much space between them that they are constantly bouncing off each other, sometimes at very high speeds. More space between the molecules of a substance means compression is that much easier.
The hardest solid known is the ADN, or aggregated diamond nanorod, which is a nanocrystalline form of diamond.
The hardest metal is the rare earth element Lutetium.The hardest solid is titanium.
both wurtzite boron nitride and mineral lonsdaleite at 58% harder than a diamond. made by Nanotechnology to rearrange a diamond
Diamond is typically considered the hardest known natural material due to its exceptional hardness and durability. It ranks 10 on the Mohs scale of mineral hardness, making it difficult to scratch or chip.
ADNR's are a special manmade form of pure carbon that are harder (and denser) than natural diamonds and manmade ultrahard fullerine. I believe the answer is lonsdaleite. It is naturally made and is 58% harder than diamonds.
Diamond is the hardest known material. Its hardness is due to the strong covalent bonds between carbon atoms arranged in a crystal lattice structure, making it resistant to scratching or deformation.
Diamond :)
On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.
Yes, they are but the hardest material in the world known to mankind is DIAMOND.
Diamond ( an allotrope of carbon) is the hardest material known.

Yes, diamonds are the hardest naturally occurring substance known to man. They are rated as a 10 on the Mohs scale of mineral hardness.
carbon dude carbon
No, diamond is not ductile. It is the hardest known natural material but is brittle and will shatter when subjected to force.

Diamond has an extremely strong covalent bonding between carbon atoms; today diamond is not considered the hardest material, Today the hardest material is Aggregated diamond nanorods.
Diamond is the hardest material known to man. Diamond is a form of carbon which has been compacted and gained a crystalline form due to intense pressure in the earth's crust. Therefore, carbon can be the hardest element.
Diamond is the hardest material on the list. It ranks as a 10 on the Mohs scale of mineral hardness, making it the hardest naturally occurring substance known.
diamond is the hardest material and if it is sharpened , then it is the sharpest material
