Aluminium Square Single Crystal

Goodfellow's Aluminium Square Single Crystal is available in 29 variations. Single crystals are widely used in fundamental research across diverse fields such as physics, catalytic chemistry, and materials science due to their precisely controlled purity, orientation, and lack of grain boundaries. For example, aluminium single crystals can serve as crystal monochromators or analyzers for x-rays and neutrons. Their uniform lattice structure also makes them ideal substrates for investigating intrinsic materials properties. By providing aluminium square single crystals in a range of orientations and dimensions, Goodfellow enables researchers to select the ideal sample for techniques like diffraction, spectroscopy, and scanning probe microscopy.
