Ga1O3P1
Gallium phosphate · GaPO4
Gallium phosphate is a stable, insulating crystalline material widely used for its piezoelectric properties in high-temperature sensors.
About Gallium phosphate
Gallium phosphate is a robust, thermodynamically stable inorganic compound that crystallizes in a structure analogous to quartz. Its wide-band-gap insulating nature makes it an excellent candidate for specialized electronic and optical components where thermal and mechanical stability are paramount.
This material is primarily utilized in high-temperature piezoelectric applications. Because it maintains its structural integrity and performance characteristics under harsh conditions, it serves as a critical alternative to more common piezoelectric materials in demanding industrial environments.
Key Properties
Cross-validated computational properties for Gallium phosphate, 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 transparent conducting oxides class.
While materials like ZnO and BaSnO3 are widely recognized as transparent conducting oxides, gallium phosphate functions as a wide-band-gap insulator. Unlike the conductive or semiconducting behavior seen in siblings such as ZnGa2O4, GaPO4 is prized for its exceptional stability and piezoelectric properties, positioning it as a specialized functional material rather than a traditional transparent conductor.
