About Titanium tetrachloride
Titanium tetrachloride is a highly significant inorganic compound characterized by its insulating electronic nature and robust thermodynamic stability. As a member of the metal halide family, it serves as a critical precursor in chemical synthesis and materials processing.
Its importance lies in its reactivity and role as a fundamental building block for advanced materials. It is widely utilized in the manufacturing of titanium-based pigments and as a primary catalyst in the polymerization of olefins, playing a central role in modern chemical manufacturing.
Key Properties
Cross-validated computational properties for Titanium tetrachloride, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
