Cobalt Disk Single Crystal

Goodfellow's line of Cobalt Disk Single Crystals comes in 89 variations. These highly pure, orientation-specific cobalt disks are ideal for fundemental research applications across physics, chemistry, and materials science. With no grain boundaries, cobalt single crystals enable precise analyses of intrinsic properties and processes. Example uses include serving as monochromators to select specific wavelengths of X-rays or neutrons, as well as electrode materials where orientation affects performance. By providing disks in a range of orientations, Goodfellow empowers researchers to systematically study how structure impacts cobalt's functionality.
