Resumen:
A new Bi3Ge3O10.5 compound has been synthesized under high pressure,
P = 7 GPa, and 700 °C. Instead of the pyrochlore that is normally stabilized under high
pressure, the Bi3Ge3O10.5 crystallizes in a KSbO3-ype crystal structure. The crystal
structure has been refined by the Rietveld method from synchrotron X-ray diffraction
data. Moreover, we have also characterized the Bi3Ge3O10.5 by X-ray photoelectron
spectroscopy, photoluminescence, and specific heat.
