Structural Characterisation of Silver Containing Bismuth-Borate Glasses by X-Ray Scattering

Abstract

The effect of silver addition to bismuth-borate glasses with low lime content on their structure is evidenced from X-ray scattering measurements. The radius of the first coordination spheres was determined from the correlation function g(r). The larger radius values obtained for the first coordination spheres by adding silver denotes a diminution of the atom packing in this system. Further atoms from the third and fourth coordination spheres occur in a less distorted configuration than in the precursor CaO-Bi 2 O 3- B 2 O 3 vitreous compound.
