Molybdenum Disk Single Crystal

Molybdenum Disk Single Crystal is a high purity single crystal product with up to 90 variations within Goodfellow's range. Single crystalline molybdenum is highly valued for applications in physics, chemistry, and materials science research due to its precisely aligned crystal lattice and lack of grain boundaries. For example, molybdenum Disk single crystals can serve as electrodes in electrochemical reactions or as monochromators for x-ray and neutron diffraction studies, where crystal orientation and purity are critical parameters. By offering numerous Disk sizes and orientations, Goodfellow enables researchers to select the optimal molybdenum single crystal for probing intrinsic materials properties or interactions at the atomic scale.
