Scandium Hydride (ScH2~3)-Powder
Characteristic
Scandium hydride, also known as scandium–hydrogen alloy, is an alloy made by combining scandium and hydrogen. Hydrogen acts as a hardening agent, preventing dislocations in the scandium atom crystal lattice from sliding past one another. Varying the amount of hydrogen controls qualities such as the hardness of the resulting scandium hydride. Scandium hydride with increased hydrogen content can be made harder than scandium.
Concentration dependent activation-energies are observed for hydrogen diffusion in scandium metal.

Application
Scandium metal is applied in optical coating, catalyst, electronic ceramics and laser industry. The main application of Scandium by weight is in Aluminium-Scandium alloys for minor aerospace industry components. Some items of sports equipment, which rely on high performance materials,it have been made with Scandium-Aluminium alloys.
Package
Vacuum pumping and argon protection, 500g or 1000g / bottle.
