Al-Cu-Fe quasicrystals are a unique group of materials with anomalous symmetry and high performance properties, such as low thermal conductivity and high hardness. The development of methods for the large-scale synthesis of these quasicrystals opens up prospects for their application in various industries, including aviation, automotive and energy.

The synthesis of quasicrystals can be carried out by various methods, including doped casting, mechanical sintering and mechanochemical synthesis. Each of these approaches has its own advantages and disadvantages, such as control over particle morphology and structure.                                                        

To achieve submicron particle size, control of process parameters such as temperature, pressure and feed metal composition is critical. The use of doping technology makes it possible to achieve the required degree of homogeneity and stability of the quasicrystalline structure.

Large-scale synthesis of Al-Cu-Fe quasicrystals opens up new horizons for creating materials with advanced properties, making them promising for use in high-performance engineering solutions.
