calcium bromide · calcium dibromide
Calcium bromide is a stable, insulating salt widely utilized as a high-density completion fluid in the petroleum industry.
About calcium bromide
Calcium bromide is a thermodynamically stable inorganic salt that functions as a wide-band-gap insulator. Its robust structural profile is evidenced by its extensive representation across multiple crystallographic databases, reflecting its well-defined chemical nature.
This compound is primarily valued for its high solubility and density in aqueous solutions. These properties make it an essential component in heavy brines used for oil and gas well completion and workover operations, where it helps maintain pressure control.
Key Properties
Cross-validated computational properties for calcium bromide, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
