Growth of a decagonal Al₇₀Ni₁₅Co₁₅ single quasicrystal by the Czochralski method

Single decagonal quasicrystals of Al₇₀Ni₁₅Co₁₅ were grown by the Czochralski method at Ar atmosphere. The grown crystals were of single decagonal phase without any secondary phases due to the peritectic reaction and contained a large single quasicrystal of cm order size. The high quality and single quasicrystallinity of them were examined by the Laue transmission photography, single crystal X-ray diffraction, and high-resolution electron microscopy investigations.
