What is the pecentage of carbon in Aggregated diamond nanorods?
100%
How might a diamond made from zircon be appraised?
A diamond is NEVER made of zircon, they can only be made of carbon.It is trivial for an appraiser to distinguish a cubic zirconia "fake" from a diamond and correctly determine the value.
What is pure carbon in the form of a diamond made of?
Diamond is an allotrope of carbon: pure carbon is made of pure carbon, by definition.
Which element is diamond made for?
Carbon
What is the difference between a molecule of sand and diamond?
Diamond is a tetrahedral network made of carbon atoms; sand is made of silicon dioxide.
Can you break Aggregated Diamond Nanorods with a hammer?
No
What is the pecentage of carbon in Aggregated diamond nanorods?

Is the diamond the hardest material?
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.
Are there other types of solids as hard as diamond?
There are a few, but all are synthesized (lab grown) and not naturally occuring. The list would be: Rhenium Diboride(ReB2), Ultrahard fullerite (C60), and Aggregated diamond nanorods, or ADNR. All three are able to scratch diamond. The hardest of all known materials is aggregated diamond nano-rods, which are ultrahard fullerenes forced together, creating small diamond rods in a random arrangement (versus the orderly arrangement of diamond).
Is diamond tougher than Aggregated Diamond nanorods?
Your operative word is 'tougher'. If you'd asked 'harder' instead, the answer would be 'no'. Tougher requires usefulness. Since your question does not relate to gemstones, but to industrial uses of the diamond mineral, and since your question doesn't yet have an application in industrial uses, your question is a scientific question. From Wikipedia: "Aggregated diamond nanorods, or ADNRs (also called a hyperdiamond), are a nanocrystalline form of diamond. These are synonymous with the more conventional (and perhaps more justified) term "nanodiamond". Nanodiamond was convincingly demonstrated to be produced by compression of graphite in 2003 and in the same work found to be much harder than bulk diamond, which makes it the hardest known material."

What is the hardest substance on the earth?
Aggregated Diamond NanorodsADNRs, 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.Its diamond
What is the the hardest substance known?
The hardest substance on earth are things called Carbon Nanotubes. It's quite some times harder than diamond earning it well above a 10 on the Mohs Scale. This object is synthetic, being made by man. However, there is another substance called Rhenium diboride that is also harder than diamond; another from of a nanotube.
What is the hardness of diamonds?
The diamond has a rating of ten (10) on the Mohs scale of mineral hardness. On an interval scale, it has an absolute hardness of 1600 compared to 1 for talc. It is the hardest naturally occurring mineral, with only aggregated diamond nanorods (also known as hyperdiamonds) being harder.
What is the hardest manufactured material?
steel boron carbide is stronger than steel I do believe To date, probably carbon nanorods. Carbon is strongest, but in might be nanorods, nanotubes, or fiber. I'm not sure. A particular arrangement of carbon called Lonsdaleite (both naturally occurring in trace amounts and manufactured) is the hardest known material to date. pure samples have been recorded to be 58% harder than diamond, however when found naturally, impurities cause the Mohs Hardness to be only 7-8 (diamond is 10 on this scale).
What is aggregated knowledge- the phrase not the company?
Aggregated knowledge would be knowledge collected from many sources.
What is the hardest substance in the world?
diamond
What does Aggregated sentence mean?
An aggregated sentence is one that is a cluster of words. It does not make sense and it is not formed properly.
