Abstract
Homogeneous glasses are formed in the Bi2O3-P2O5 system up to 35 mol% (63.8 wt%) Bi2O3. In property vs composition plots, the thermal expansion coefficient and tan δ exhibit minima, and hardness and activation energy for conduction show maxima at about 20 mol% Bi2O3. The deformation temperature of the glasses also increases abruptly at this composition. This anomalous behavior is interpreted in terms of a change in the function of Bi3+ ions from network formers to network modifiers.
