The surface tension of the molten system KF-K2MoO4-B2O3 has been determined
using the maximum bubble pressure method. The error in the surface tension
measurement was estimated to be +/- 1 %. On the basis of the obtained data
the composition dependence of the surface tension and of the surface tensi
on excess of the investigated system was calculated and compared with the r
esults of other previously determined physicochemical properties. The resul
ts are discussed in terms of the anionic composition.
