A synthesis method involving shock compression has been used to create quasicrystals, with reports of both icosahedral and decagonal quasicrystals being produced. The exact composition of the synthesized quasicrystals is unclear, with one report mentioning a five-component icosahedral quasicrystal and another referencing decagonal quasicrystals. Additionally, quasicrystals have also been discovered in a micrometeorite from Southern Italy, composed of aluminum and copper alloys.
