Quasicrystals of Al-Cu-Co alloy have been obtained by utilizing a double spherical mirror furnace to melt the combined high-purity constituent elements. This double spherical furnace employed a 600 W lamp, and was used to initially heat the alloy components to 1600 K in about 30 s. This temperature was maintained for 60 to 120 s, and the material was then cooled to room temperature in approximately 200 s. The resulting crystals had a rod-like shape and exhibited decagonal symmetry, as shown by their electron diffraction pattern. Quasicrystals were obtained with lengths of between 1 and 2 mm and diameters of about 30 μm.
