Tungsten Single Crystal

W

Application: Metal single crystals are required among others for basic research (surface physics, catalytic chemistry, investigation of material properties, etc.) and for monochromators (for X-ray, neutrons, etc.).

Tungsten is generally obtained as a dull grey powder, which is difficult to melt. The bulk metal is silvery-white, and resists attack by oxygen, acids and alkalis. Tungsten is used in alloys, to which it imparts great strength, in light bulb filaments and cutting tools.
