Is there anything harder than diamond? Thanks.?

Answer 1

A woman's heart!! Am i right?

Answer 2

Obviously, the larger the carat, the more expensive! One carat diamond earrings are perfect, but they'll set you back a whole lotta money! Look on the H Samuel website or Ernest Jones, I'm sure you'll find some cheap ones there.

Answer 3

Diamond is a graphite material, which is a form of carbon. Currently it is the hardest natural mineral, and nothing in nature has been found to be harder.

Answer 4

What's Harder Than Diamond? Graphite!
Of course, we're not talking pencil lead. The super-hard graphite was formed by focusing an intense x-ray beam onto a small area of graphite, applying pressures on the order 170,000 times the pressure at sea level. The graphite formed from this process was hard enough to crack the diamond anvil upon which it was formed. For more information, read the article at ScienceDaily News.

New Material Breakthrough: Super-hard Graphite Cracks Diamond
It is hard to imagine that graphite, the soft "lead" of pencils, can be transformed into a form that competes in strength with its molecular cousin diamond. Using a diamond anvil to produce extreme pressures and the ultra-brilliant X-ray beams at the Advanced Photon Source in Illinois, scientists with the High-Pressure Collaborative Access Team (HPCAT)* have surmounted experimental obstacles to probe the changes that graphite undergoes to produce this unique, super-hard substance. The study is reported in the October 17, issue of Science.

--------------------------------------------------------------------------------
"Researchers have speculated for years on the extreme conditions that might change the molecular structure of graphite into a super-hard form that rivals diamond," said Wendy Mao, the study's lead author from the Carnegie Institution's Geophysical Laboratory in Washington, D.C., and the University of Chicago. "This experiment is the first to determine quantitatively how the bonding in graphite changes under high-pressure conditions. Conventional methods limited our observations to surface studies of the material," she stated. "Now, with the super high-intensity X-rays of the Argonne facility and with our team's technology to focus the entire beam to a small spot, we've been able to look at the material in the diamond-anvil cell while under high pressure. We've overcome the obstacles of the past," she concluded.

Graphite and diamond are both made of carbon. The geometric arrangement and spacing of the carbon atoms is what makes the materials differ in appearance and strength. The atoms in graphite are arranged in layers that are widely spaced. The atoms in diamond, on the other hand, are tightly linked producing a strongly bonded structure. The HPCAT scientists subjected graphite to pressures that are equivalent to 170,000 times the pressure at sea level ( 17 gigapascals). "We were able to see how the structure changed at the atomic level when the graphite was squeezed into the super-hard form," remarked co-author Dave Mao of Carnegie's Geophysical Laboratory. "The graphite that resulted from our experiment was so hard that when we released the pressure we saw that it had actually cracked the diamond anvil."

The super-hard from of graphite opens the door to a myriad of applications in industry particularly as a structural component.

Answer 5

No. On the Mohs Scale of Relative Mineral Hardness, the Diamond is the top of the list. 10.

Answer 6

Is Anything Harder Than Diamond

Answer 7

nope, its lvl 10 of the mohs hardness scale, but must be pure diamond. imperfect diamond isnt as hard.

Answer 8

Nein.

Answer 9

My ex-girlfriend's head.


And the answer is no.

Answer 10

i dunt think so
