The Structure and Properties of Glasses in the Nb2O5-B2O3-K2O System
The structure of nioboborate glass was studied with a high power ro-tating anode type CuKαX-ray diffractometer.Based on the warren equation
a new way resolving the redical distribution function was established.It was comparatively simple
especially for the analysis of RDF of polycompo-nent glass system because it was concerned with fearer factors. Using this way the structure model of nioboborate glass was ob-tained.A loose construction is the feature of these glasses.That is to say the valume of structure unit in the glass is sufficientlylarge
there exist agre-at numberof wider hollows in the structure.This is the reason why the niobo-borate glass has high dispersion and comparatively low density.Besides this
some glasses in the system also have high conductance.
