摘要：

The coordination structure around Bi atoms has been studied in Li2O-Bi2O3-B2O3 glasses by X-ray diffraction method. It was found that Bi atoms were coordinated by five or six oxygen atoms. The number of Bi atoms around a Bi atom through Bi-O-Bi bonds increased with an increase in Bi/O ratio. It was inferred that BiOx polyhedra were clumped in the glasses, although BiOx polyhedra were more clumped in Li2O-Bi2O3-B2O3 glasses than in Bi2O3-B2O3 glasses.
