项目摘要
In the present work, it was aimed to determine the major driving force for Marangoni convection during the FZ growth of silicon carbide. The experimental apparatus of the maximum bubble pressure method for alloy samples was fabricated, and then measurements of surface tensions of Fe-Si-C alloys were conducted at 1250~1450℃. The surface tensions of binary Fe-Si alloys and ternary Fe-Si-C alloys are similar, and the carbon effect on the surface tension was not observed. Accordingly, it was speculated that the Marangoni flow is driven by the temperature difference in the Fe-Si solvent during the solution growth process.
本工作旨在确定碳化硅快速生长过程中Marangoni对流的主要驱动力。研制了合金最大气泡压力法实验装置,并在12 5 0~14 5 0℃范围内测量了Fe-Si-C合金的表面张力。二元Fe-Si合金和三元Fe-Si-C合金的表面张力相似,未观察到碳对表面张力的影响。据此推测,Marangoni流是由溶液生长过程中Fe-Si溶剂中的温差驱动的。
