BaH2
Barium hydride · Barium dihydride
Barium hydride is a stable, semiconducting inorganic compound primarily studied for its hydrogen storage properties and solid-state chemical behavior.
About Barium hydride
Barium hydride is a binary inorganic compound composed of barium and hydrogen. As a thermodynamically stable material situated on the convex hull, it represents a robust phase within its chemical system, supported by extensive structural data across multiple databases.
This semiconducting material is primarily investigated for its chemical reactivity and its potential utility in hydrogen storage research. Its stable configuration makes it a significant subject for studies focusing on metal hydride behavior and solid-state chemistry.
Key Properties
Cross-validated computational properties for Barium hydride, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
