| Research Abstract |
To give the basis of the aperiodic-crystal engineering, for quasicrystals and related approximant crystals, single crystal growths and crystal structure analyses have been attempted in several alloy systems. Single crystals, with a typical size of several millimeters of a decagonal phase with 1.6 nm periodicity and approximant crystals in the Al-Ni-Ru system were grown successfully by the flux method. Single crystals of a higher-order, 3/2-2/1, approximant to a decagonal phase with 1.2 nm periodicity have also been grown successfully. The flux method makes possible to grow single crystals of Al-based quasicrystals, which contain high-melting-point metal as constituent elements, at relatively low-temperatures.
