-60 mesh with 99.5% purity; resembles CaH2 in both properties and reactivity [KIR80] [CER91]

Strontium Hydride, SrH2, is formed from the metal in the presence of hydrogen, under similar reaction conditions to that of calcium. Because of its great resemblance to calcium, little practical usage has evolved. It is an electronically neutral reagent chemical. In contact with water, it decomposes to form hydrogen:
SrH2＋H2O→Sr(OH)2＋H2
SrH2 has the same type of structure as CaH2 except that the cell parameters are: a＝3.875 ?, b＝6.364 ?, c＝7.343 ?, α＝β＝γ＝90°, cell volume＝181.08 ?³.

It can be produced by the direct combination of hydrogen and strontium or by reducing strontium oxide or strontium chloride with hydrogen.
