The manufacturing processes for quasicrystals are complex and require precise control over various parameters. One of the primary methods for producing quasicrystals is rapid solidification, which involves cooling molten alloys at extremely high rates, typically exceeding 106 K/s. This process prevents the formation of periodic crystal structures and allows for the creation of quasicrystalline phases. Melt spinning is a commonly used technique for rapid solidification, where a thin stream of molten alloy is ejected onto a rapidly rotating copper wheel, resulting in the formation of thin ribbons or flakes of quasicrystalline material.

Another important manufacturing process is physical vapor deposition (PVD), which can produce high-quality quasicrystalline thin films. In this method, the constituent elements are vaporized in a vacuum chamber and deposited onto a substrate. Various PVD techniques, such as sputtering, electron beam evaporation, and pulsed laser deposition, can be employed to create quasicrystalline coatings with controlled composition and thickness.

Mechanical alloying is also utilized for quasicrystal production, particularly for bulk samples. This solid-state process involves high-energy ball milling of elemental powders or pre-alloyed materials, leading to the formation of quasicrystalline phases through repeated fracturing and cold welding of particles. The resulting powders can be consolidated using techniques like hot pressing or spark plasma sintering to create bulk quasicrystalline materials.

For precision measurement applications, the manufacturing of quasicrystal-based devices often requires additional processing steps.
