Surface Tension of the Molten CaO-SiO<sub>2</sub> Binary and CaO-SiO<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub> Ternary Systems

Abstract

Th e surJace tension oj the moLten CaO -Si0 2 binmy and CaO-S i0 2 - AI 2 0 3 ternmy ~ys tem at 1550 and 1 600C has been measured by means oj a maximum bubbLe pressure method. Th e measured values give the Jollowing expressionsJor the sUlface tension , )"c, in dynes /Jer centimeter:
