Such crystals consist of a completely unique atomic structure.
Physicists have discovered ultra-rare quasicrystal in the piece was found in Chukotka in 2011 meteorite.
This is only the third time in history that scientists have discovered in nature, this strange crystal with unusual symmetry.
Found the quasicrystal has symmetry of an icosahedron — a regular convex icosahedron, each of the faces of which is an equilateral triangle. He was found by a team led by geologist Luca Bindi from the University of Florence in Italy.
The authors believe that it was formed under high pressures and temperatures 1.2 thousand degrees Celsius as a result of collision of celestial bodies in space.
“We have found three different types of quasi-crystals in the same meteorite, and this has a chemical composition, which have never been seen on quasicrystals. This suggests that there is still plenty of quasicrystals, which we do not know”, – said the representative of the research team, Paul Steinhardt of Princeton University.
We add that such crystals consist of a completely unique atomic structure, which basically combines the symmetric properties of the crystal and the chaos in amorphous solids.
It is interesting that, although the quasicrystals are incredibly rare in nature – or at least on Earth, they are very easy to do in the lab, and synthetic quasicrystals are now used, for example, all led lights.
