Abstract
Since physico-chemical properties of liquid alloys, molten salts and molten slags affects various phenomena in crystal-growth process, the information on those properties is indispensable to control and design new technical processes. We sometimes, however, come across a situation of lacking those information, and we have to estimate the properties from some fundamental physical quantities. This paper describes some procedures to predict the surface tension of liquid alloys, molten salts and molten slags. In addition, some useful literatures will be given on the prediction of the properties.
