Al2H2Na4O18Si6
natrolite · needle stone
Natrolite is a hydrated sodium aluminosilicate zeolite mineral valued for its porous framework and ion-exchange capabilities.
About natrolite
Natrolite is a naturally occurring tectosilicate mineral belonging to the zeolite group. Characterized by a robust aluminosilicate framework, this compound exhibits wide-band-gap insulating behavior, which is typical for its class, and maintains high thermodynamic stability under standard conditions.
Its structural architecture is defined by interconnected channels and cavities that allow for the selective adsorption and exchange of ions. This unique porous nature makes it a vital material for industrial processes involving molecular separation and catalytic support.
Key Properties
Cross-validated computational properties for natrolite, 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.

How It Compares
Within the aluminosilicates and zeolite frameworks class.
Within the diverse family of aluminosilicates, natrolite stands out for its high degree of hydration and open framework structure compared to denser, non-porous members like Al2SiO5. While compounds such as NaAlSi3O8 are essential components of the Earth's crust, natrolite is specifically valued for its functional porosity, which distinguishes it from the more rigid or less permeable silicate frameworks found in its class.
