抄録

The surface tension of molten lead silicates containing 0 to 60 mole % SiO2 was measured by a dipping cylinder method using an automatic balance. The surface tension increased with rising temperature and with decreasing PbO-content. On the curves showing the relationship between surface tension and composition of silicates, small discontinuities were observed at the compositions corresponding to 2PbO·SiO2and PbO·SiO2. It was found that the temperature coefficient of surface tension was about +0.02. Furthermore it should be noted that the surface tension at 100°, 200° and 300°C higher than liquidus temperature varied linearly with compositions and showed three straight lines intersection at the composition coresponding to about 25 and 50 mole % SiO2.
