Abstract

The surface tension of Bi ₂O ₃-B ₂O ₃-SiO ₂ melts was measured using the ring method over the temperature range 973-1573 K. The composition and temperature dependences of the surface tension were investigated. The surface tension of Bi ₂O ₃-B ₂O ₃-SiO ₂ melts showed a maximum near 60-70 mol% Bi ₂O ₃ and decreased with increasing B ₂O ₃/SiO ₂ ratio at 1373 K. By assuming a linear relationship between the surface tension and the Bi ₂O ₃ content of binary silicate melts, the surface tension factor of Bi ₂O ₃ was determined to be 211 mN m ^-1 at 1373 K. The surface tension values calculated using the surface tension factor of each single component showed the largest deviation from the measured values when the Bi ₂O ₃ content was around 50-60% and were dependent on the B ₂O ₃ content. The temperature coefficient of surface tension had positive values at low Bi ₂O ₃ contents (less than 30-40 mol%) and negative values at high Bi ₂O ₃ contents.
