Diamond may remain the preferred material for wedding rings, Lil' Wayne's birthday gifts, and Damien Hirst sculptures, but it looks like girls' best friend will have to relinquish its title as the hardest natural substance known. The new title holder: mysterious carbon compounds found in a Finnish meteorite.
Writing in the journal Earth and Planetary Science Letters, Tristan Ferroir, a professor at the University of Lyon, France, reports that his team has discovered two new materials harder than the precious stone. Ferroir discovered the compounds when a diamond-coated sander failed to file down pockets of the compound nestled inside of the meteorite, which fell in 1971.
Ferrior has seen carbon nodules, fused by the heat of atmospheric entry, resist the diamond sander before, but only in one direction. These new minerals are the first ever to remain uniformly invulnerable from every direction.
Of the two minerals, one is a kind of diamond that had been predicted by scientists decades ago, but never observed in nature. The other is truly novel, having formed from fused sheets of graphite in a manner similar to the method used in the production of artificial diamonds.
Due to the small quantities of each mineral, Ferroir has been unable to test precisely how hard they really are. For now, all we can do is speculate about the limits of their hardness, and hope that they don't weaken Superman.
Is that really a diamond in the picture or what? The facets looks really dull and curved. Looks like a piece of glass that someone took a blow torch to and somewhat melted the edges.
Exiting stuff, can't wait to see the TWITF shirt; a broken bayonet on a moon rock, with nasa's constellation unfinished and an X shape in space like background. Or, that is what I predict it will be
I've already heard of these substances, one is the result of meteor impacts the other in in volcanoes
@rpenri: The rock on the picture isn't what they found in the meteorite.
@Jedigeek93: Those substances were never referenced before. Until this day, the harder thing we have was diamond. At 10 on the Mohs scale. They were able to predict one of the two, because we're getting to know carbon.
We can expect that those substances result from high temperature and high pressure. But we don't have those conditions here on earth.
So, would the Mohs scale go past ten? Or would diamond move down and this substance would become ten?
Wasn't asking if it was. Did you even read my post?
Anyone else that read my post, can you explain to Fredl1886 what it was I was asking because apparently I cannot ask a more simple and straightforward question than that.
Why write an article dealing with diamonds / carbon nanotubes and insert a picture of cubic zirconium or other pieces of glass? Because real cut diamonds don't have softened edges like that. That looks like it almost came out of a mold. How hard is it to Google "diamonds" and find a picture of a real "diamond"?
How much will it cost?
Furthermore, anyone who has seen a real diamond can tell that "rock" in the picture is nothing more than melted sand. There's no fire, no brilliance or anything else typical of quality cut diamonds. That's a few of the reasons why people like diamonds, because they're "shiny" and "sparkly".
I should know, I was trying to re-create diamonds in Lightwave 3D and non of the plugins and filters could put out "real" looking diamonds (their dielectric material is close, but no cigar). Everything looked like glass. Imported the scene into Maxwell Render and used their IOR (index of refraction) file for diamonds and got better results.
I believe the material is called Lonsdaleite? I read a different article about this very thing a few hours before it was posted here. That article gave that as the name of the material. It has been created in labs before and it is like 50%-60% harder than diamond.
Oh, heck no, you did NOT just make a MegaMan II Quickman stage reference!!!!!! Nicely played!
Now the Mohs scale goes to eleven. It's one harder isn't it?
Hyperdiamond is supposedly the hardest material known.
My Tachyonic Auntie Persephone
maybe it's a 15 on the Mohsscale...........oh dear god the possibilities would be endless!
Wow, amazing. Wish one of those would land in my back yard!
...wow. most of you guys are really rude/deppressing, are all my fellow nerds this way? Anyway, this stuff can be incredible! do you know what this can do?... Me neither. but one things for certain; we are just begining to understand carbon.
live like it's your last day. (Cause it just might be.)
is it just me or am i the only guy that has such a f-cked up schedule so i'm the only one up at this hour?
Hey myfavnmbr12 ! Why call yourself/us nerds? Why not refer to the knuckle dragging, chest beating know nothings, as Gronks? Nerd at least used to be a negative term.
Live well my friend! May your path be straight, and your burden light.
Does it have the electric properties that carbon nanotubes have... that would really make it special.
So with this being a natural process, do we dare to hope for room temperature superconducting crystals of scale from carbon sometime down the road?
