Research Abstract

Surface tension and density of high temperature melts, especially liquid silicon were measured with the levitated drop method using microgravity environment which is the longest term, 10 seconds, and the highest quality on the earth.
The results can be summarized as follows ;
(1) A measurement method for surface tension and density of high temperature melts under microgravity environment.
(2) Surface oscillation mode of melt caused by surface tension was analyzed.
(3) Surface tension values obtained in this work were more reliable than those in previous works.
(4) Surface tension and density were measured under supercooled condition because of containerless process.
(5) Surface tension of liquid silicon was not affected by an oxygen partial pressure in an atmosphere in the present experimental condition.
(6) Surface tension and its temperature coefficient of liquid silicon were 734 mN/m at the melting point and 0.069 mN/mK, respectively.
(7) An applicable range of correction equation was obtained for a calculation of surface tension.
(8) Positioning of liquid drop must be controlled to measure the density by the levitated drop method.
