GaPO does not occur in nature; thus it must be grown synthetically.

GaPO has many advantages over quartz for technical applications, like a higher electromechanical coupling coefficient in resonators, due to this doubling.

GaPO is isotypic with quartz, possessing very similar properties, but the silicon atoms are alternately substituted with gallium and phosphorus, thereby doubling the piezoelectric effect.

It floods the banks, extends in great lagoons over a monstrous waste of country, and forms a huge district, called locally the Gapo, which is for the most part too marshy for foot-travel and too shallow for boating.

GaPO possesses, in contrast to quartz, no α-β phase transition, thus the low temperature structure (structure like α-quartz) of GaPO is stable up to 970 C, as are most of its other physical properties.

Further exceptional properties of GaPO for applications at high temperatures include its nearly temperature independent piezo effect and excellent electrical insulation up to 900 C. For bulk resonator applications, this crystal exhibits temperature compensated cuts of up to 500 C while having Q factors comparable with quartz.
