Cobalt Top Hat Single Crystal
Cobalt Top Hat Single Crystal is one of Goodfellow’s single crystal offerings, with 15 variations available. Single crystals like these cobalt samples are valued for their precisely aligned atomic structure and purity, with no grain boundaries. Their orientation can be aligned along desired crystal planes. Applications take advantage of these qualities, using the cobalt crystals in fundamental physics research, electrochemistry studies, and as monochromators or analyzers for x-rays and neutron beams. Other uses arise in electronics and sensors.
