Zc. Wang et al., HIGH-TEMPERATURE ISOPIESTIC STUDIES ON THE TERNARY SLAG PBO-SIO(2)-B(2)O(3) AT 1273-K, Metallurgical transactions. B, Process metallurgy, 25(1), 1994, pp. 103-109
An improved high-temperature isopiestic technique has been applied to
the ternary slag PbO-SiO2-B2O3 and its binary subsystems PbO-SiO2 and
PbO-B2O3 at 1273 K. The isopiestic measurements agree well with the li
terature data for the two binaries. Each entire isoactivity curve of P
bO in the ternary slag was determined by only one experiment. The acti
vities of SiO2 and B2O3 were then calculated analytically. The measure
d and calculated results for the ternary slag approximately fit a part
ial ideal solution model proposed previously.
