CaCl3Rb is a thermodynamically stable, insulating ternary halide compound composed of calcium, chlorine, and rubidium.

About CaCl3Rb
CaCl3Rb is a complex halide compound composed of calcium, chlorine, and rubidium. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement within its chemical system. Its electronic character is defined by a wide band gap, classifying it as an insulator with significant potential for specialized dielectric or optical applications.
This material is characterized by a high degree of structural diversity, with multiple reported configurations across various databases. Its stability and insulating nature make it an interesting subject for fundamental studies in solid-state chemistry, particularly for researchers investigating ternary halide systems and their underlying lattice dynamics.
Key Properties
Cross-validated computational properties for CaCl3Rb, 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.
