Bismuth Square Single Crystal is one of the many single crystal products available in Goodfellow's extensive range. With 10 variations, these high purity crystals grown in specific orientations are used in fundamental physics and chemistry research as well as x-ray and neutron monochromators thanks to their lack of grain boundaries. The oriented atomic structure also makes them ideal for investigating materials properties. Other applications include crystal analyzers and electrodes where purity and orientation are paramount.
