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.
Diamond is the hardest natural material known. It is composed of carbon atoms arranged in a strong crystal lattice structure, which gives it its extreme hardness.
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.
it is the element of grphite and or dinmde
On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.
Diamond ( an allotrope of carbon) is the hardest material known.

Diamond is the hardest natural material known. It is composed of carbon atoms arranged in a strong crystal lattice structure, which gives it its extreme hardness.
Diamond is the hardest known natural material on Earth, scoring a 10 out of 10 on the Mohs scale of mineral hardness.
No, crystalline boron is not the hardest material. Materials like diamond, which have a higher hardness on the Mohs scale, are considered to be harder than boron. Boron is known for its hardness and ability to resist wear, but it is not the hardest material overall.
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.
Metal is generally considered a hard material, but it is not the hardest material in the world. There are materials like diamond and boron nitride that are much harder than most metals. Hardness is a measure of a material's resistance to scratching or indentation, and different materials have different levels of hardness.
No. Diamond is the hardest mineral and it is not malleable or plastic.
Diamond is the hardest mineral mined in the north of Western Australia. It has a hardness of 10 on the Mohs scale, making it the hardest natural material known to man.
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.
Yes, diamonds are the hardest known natural material on Earth. They are ranked as a 10 on the Mohs scale of hardness, which is a scale that measures the hardness of minerals, with 10 being the highest.
Diamonds are the HARDEST natural material. Mankind has created harder artificial materials.
