Suppression of Marangoni Convection with Oxide Films

摘要

This research is an effort to determine whether surface tension driven convection in molten tin can be eliminated by the formation of one to several monolayers of oxide on the molten tin surface. Initial work is presented describing Auger and electron loss spectroscopies used to detect SnO and SnO sub 2 on molten tin surfaces in a UHV system. Progress on efforts to produce and monitor controlled oxide layers of 8 to 20 A upon floating zones in a disk geometry is presented. (ERA citation 07:022324)
