Description
Barium Hydride (BaH2) forms in a manner similar to that of strontium
hydride with the PbCl2 type of structure. It too has
found little usage in Industry. Cell parameters are:
a＝4.168 ?, b＝6.792 ?, c＝67.858 ?, α＝β＝γ＝90°,
Cell volume＝222.45?
3.
Chemical Properties
gray crystal(s); -60 mesh with 99.7% purity; sensitive to moisture; resembles CaH2in properties [KIR80] [CER91] [STR93]
Safety Profile
A poison. Rapidly decomposed bywater and acids. In powder form, it ignites spontaneouslyin air and reacts vigorously with water. Coarser materialignites when heated in oxygen. Moisture-sensitive, reactswith H2O with formation of Ba(OH)2 and H2. Decomp
