Abstract

The surface tensions of xPbO-(100-x) B₂O₃ (x = 30-80 mol%) and xBi₂O₃-(100-x) B₂O₃ (x = 0-100 mol%) melts were measured using the ring method over the temperature range 973 to 1373 K. The compositional and temperature dependences of surface tension were investigated. Addition of PbO and Bi₂O₃ to B ₂O₃ increased the surface tensions of their respective PbO-B₂O₃ and Bi₂O₃-B ₂O₃ melts. The surface tension showed a maximum at 60 mol% PbO in the PbO-B₂O₃ melts and at 70-80 mol% Bi ₂O₃ in the Bi₂O₃-B₂O ₃ melts. The temperature coefficient of surface tension was examined on the basis of its relationship to the structure, and it was suggested that the temperature coefficient of surface tension decreases with an increasing content of four-coordinated boron.
