wollastonite · calcium metasilicate
CaSiO3 is a stable, insulating calcium silicate mineral that is widely utilized in industrial manufacturing and geological research.
About wollastonite
CaSiO3 is a robust calcium silicate compound that exists as a thermodynamically stable phase. Its electronic character is defined by a wide band gap, classifying it as a highly effective electrical insulator that remains chemically inert under standard conditions.
This material is widely recognized for its structural versatility, appearing in numerous polymorphic forms. It serves as a fundamental component in mineralogy and materials science, where its stability and insulating nature are leveraged for high-performance industrial applications.
Key Properties
Cross-validated computational properties for wollastonite, aggregated across 4 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.
