tin phosphate · stannous phosphate
Tin phosphate is a thermodynamically stable, wide-gap insulating oxide used in specialized optical and dielectric applications.
About tin phosphate
Tin phosphate is a thermodynamically stable oxide compound belonging to the class of transparent conducting oxides. Its electronic character is defined by a wide band gap, positioning it as an insulating material rather than a traditional conductor in its pure form.
This compound is notable for its structural diversity, with numerous reported configurations. Its stability on the convex hull makes it a reliable candidate for research into dielectric layers and specialized optical coatings where wide-gap materials are required.
Key Properties
Cross-validated computational properties for tin phosphate, aggregated across 2 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 transparent conducting oxides class.
Unlike BaSnO3, which is frequently utilized for its conductive properties in electronic devices, tin phosphate acts primarily as an insulator within the broader family of transparent oxides. While many siblings like ZnO are studied for their high carrier mobility, this compound is better suited for applications requiring high transparency combined with electrical resistivity.
