Niobium Top Hat Single Crystal

Goodfellow offers a range of Niobium single crystals, including the Niobium Top Hat Single Crystal, available in 15 variations. As a high purity single crystal with no grain boundaries, Niobium Top Hat Crystals are ideal for applications in fundemental research. For example, they can serve as crystal monochromators or analyzers for x-rays and neutrons. The specific orientation and purity of these single crystals also make them useful for investigating materials properties and as electrodes in catalytic chemistry research.
