Tantalum Square Single Crystal is one of 30 variations in Goodfellow's range. Single crystals like Tantalum Square Single Crystal are used in fundamental research across physics, catalytic chemistry, and materials properties investigation. They can also be used as crystal monochromators or crystal analyzers for x-rays and neutrons as well as electrodes. The purity, lack of grain boundaries and specific orientation of single crystals make them ideal for these applications.
