Question

Discuss the preparation and properties of scandium dihydrides compounds.

Answer 1

This is a very common material in alloy science labs... They are created while combining scandium and hydrogen.

Hydrogen acts as a hardening agent, which prevents dislocations in the scandium atom crystal lattice

Depedning on the amount of hydrides required, i.e. in this case 2 hydrides or "dihydride" ... we will set t o a specific hardenning value.

As we increase H the harder the scandium alloy.

It can also be formed via progressive hydrogenation of scandium foil with hydrogen
