Description

White chips or powder(s), 99.99995% purity [ALF93]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.
