Witherite · barium carbonate
Barium carbonate is a stable, insulating inorganic compound widely used as a source of barium in the glass, ceramic, and electronics industries.
About Witherite
Barium carbonate is a naturally occurring mineral and a synthetically produced chemical compound characterized as a wide-band-gap insulator. Its high thermodynamic stability ensures it remains a reliable and consistent precursor in various high-temperature chemical processes. The compound is widely utilized in industrial applications ranging from the production of specialty glass and optical lenses to the synthesis of complex electroceramic materials. Its ability to act as a stable source of barium ions makes it indispensable in modern materials engineering.
Key Properties
Cross-validated computational properties for Witherite, 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.
