Tantalum Top Hat Single Crystal

Tantalum Top Hat Single Crystal comes in 15 variations from Goodfellow. Single crystals like these are integral to research in physics, chemistry, and materials science, thanks to their precisely-controlled purity, orientation, and lack of grain boundaries. For example, the Tantalum Top Hat Single Crystal could be used as a monochromator to isolate specific wavelengths in an x-ray diffraction experiment studying the crystal structure of a new alloy. Its oriented atomic lattice allows high-resolution scattering essential for revealing the alloy's nanostructure. With 15 variations, Goodfellow's Tantalum Top Hat Single Crystals provide researchers customizable tools for probing the fundamentals of matter.
