Figure 13. Surface of the SA-sample analyzed with the confocal laser scanning microscope. The top images show the sample’s surface before coming into contact with molten salt and the bottom two images show the surface after molten salt contact. Next to the laser images (a,c), the corresponding optical images are displayed (b,d). No significant change in the surface can be seen. The results of the confocal laser scanning microscopy for the other two droplets do not differ qualitatively.
