It is Beta Carbon nitride ( β-C3N4)
No. I don,t know what is but diamond is one of the hardest. Besides, steel is an alloy of iron and carbon, not a naturally occurring material.
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.
Diamonds are the HARDEST natural material. Mankind has created harder artificial materials.
Diamond is the hardest material made by man. It is composed of carbon atoms arranged in a strong crystal lattice structure. Its hardness is due to its unique atomic structure, which makes it highly resistant to scratching or indentation.
Diamond is the hardest known natural material on Earth, scoring a 10 out of 10 on the Mohs scale of mineral hardness.
Diamond is an allotropic form of carbon.
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.
The hardest naturally occurring substance is called diamond. It is a form of carbon.
diamond is the hardest material and if it is sharpened , then it is the sharpest material
Hardest material ever FOUND so far is still diamond because it's produced by nature. Nano-materials are proven to be harder than any diamond but since it's man made it can not be "found". It's engineered. So the question for this nano variants should be - how hard do you need it to be ?
Diamond ( an allotrope of carbon) is the hardest material known.
