Abstract
Density, Vickers' hardness, transformation temperature and thermal expansio n of xZn0.2xPbO.(100-3x)B2O3 glasses have been investigated as a function o f composition. Variations of the properties around 50 mol% (ZnOt-PbO) are a ttributed to nonbridging oxygen ions formed in the borate matrix. Parameter s are given to calculate the density in the ZnO-PbO-B2O3 glasses Results in dicate that the fraction of modifier oxide given from a ZnO content is lowe r than that given from an equal PbO content.
