AbstractMarangoni convection (MC) has been studied in a NaNO3-floating zone by flow visualization and temperature measurements under 1-g and under 0.4 g (sounding rocket TEXUS IIIa). The effects of surface tension forces and buoyant forces have been separated by suppression of MC with a surface contamination. MC is the dominating flow in small volumes. Time dependent MC in floating zones occurs for different directions and levels of gravity.
