Cobalt Square Single Crystal
Cobalt Square Single Crystal
Cobalt Square Single Crystal is 1 from a range of Goodfellow's single crystal products. Single crystals like this cobalt specimen are highly valued for properties such as their purity, lack of grain boundaries, and specific orientation. These attributes make cobalt single crystals ideal for use in fundamental research in fields like physics, catalytic chemistry, and materials science. For example, cobalt single crystals can serve as crystal monochromators or analyzers for x-rays and neutrons.
