Quasicrystals were observed for the first time Dan Shechtman in experiments on diffraction of electrons on the alloy bystroohlazhdёnnom Al6Mn, held on 8 April 1982, for which he in 2011 was awarded the Nobel Prize in Chemistry.
There are two hypotheses about why quasicrystals are (metastable phases. According to one hypothesis, the stability due to the fact that the internal energy of quasicrystals is minimal compared to the other phases.
Deterministic description of the structure of quasicrystals required to specify the position of each atom, with the corresponding model structure should reproduce the experimentally observed diffraction pattern.
The company"QuasiCrystals" - a young and dynamic company with its own scientific and innovative laboratories and research centers, having a full production cycle of quasicrystals in Russia. This allows you to constantly upgrade and improve the technology of quasi-crystals, as well as to promote and develop their new applications for unique materials with new properties.
Our team consists of young and promising employees: scientists and engineers under the direction of Yuri Abuzina collaborating with the National Research Technological University "MISA" and the Kurchatov Institute, as well as investment managers Nanocentre Dubna.
In the laboratory of TC "quasicrystals" it has developed a new method of producing single-phase quasi-crystalline alloy powder of Al-Cu-Fe (Al 65%, Cu 20%, Fe 15%).
● the initial mixture of powders Al, Cu and Fe, taken in the desired ratio, is stirred and heated in an oxygen-free atmosphere to 800-1100 & deg; C and kept at this temperature for 1-2 hours.
● obtained sintered pulverized formation of the desired size (from 10 to 100 microns). Stirring is carried out manually in a liquid evaporating under the thrust of a plasticizer for at least 1 hour to obtain a homogeneous mixture and to increase its viscosity.
