• Description: Bismuth germanate is a cubic crystal with the formula, Bi4Ge3O12. It has the “evlitine” structure. A less common composition is Bi12GeO20 . The unit cell consists of three GeO3 tetraheda arranged in a building block. These units are arranged in a cubic close-packed structure as shown in the above diagram. The crystal structure of tetrabismuth tris(germanate), Bi4Ge3O12 (I3d, Z =4), is stable to at least 7.30 GPa, as demonstrated by hydrostatic single-crystal XRD measurements in a diamond anvil cell at room temperature.
• Uses: Scintillator crystal in nuclear physics, high-energy physics, geology, and nuclear medical imaging applications including PET, X-ray CT and positron CT; in electromagnetic calorimeters. Bismuth germanate is used in detectors in particle physics, aerospace physics, nuclear medicine, geology exploration, and other industries. Bismuth germanate arrays are used for gamma pulse spectroscopy. BGO crystals are also used in detectors for positron emission tomography. Bismuth germanate has a high “electrooptic coefficient” (3.3 pm/V for Bi12GeO20) making it useful in nonlinear optics for building “Pockel cells”. It can also be used for photorefractive elements useful in the ultraviolet part of the electromagnetic spectrum. Bismuth germanium oxide is used as an organic chemical synthesis intermediate.
