Chrysotile · white asbestos
Mg3Si2H4O9 is a stable, insulating magnesium silicate mineral often recognized for its fibrous crystalline structure.
About Chrysotile
Mg3Si2H4O9 is a naturally occurring hydrated magnesium silicate that exhibits a distinct wide-band-gap insulating electronic profile. As a thermodynamically stable phase on the convex hull, it maintains structural integrity under a variety of geochemical conditions, making it a significant subject of study in mineralogy and materials science.
Its unique structural arrangement allows for the formation of characteristic fibrous habits, which have historically defined its utility in various high-performance applications. Because of its stability and insulating nature, it remains a critical reference point for understanding the behavior of complex magnesium-based silicates in the Earth's crust.
Key Properties
Cross-validated computational properties for Chrysotile, 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.
