Abstract

A test of lithium wettability was performed in high vacuum (< 3 × 10^-4 Pa). High magnification images of Li droplets on stainless steel substrates were produced and processed using the MATLAB^® program to obtain clear image edge points. In contrast to the more standard "θ/2" or polynomial fitting methods, ellipse fitting of the complete Li droplet shape resulted in reliable contact angle measurements over a wide range of contact angles. Using the ellipse fitting method, it was observed that the contact angle of a liquid Li droplet on a stainless steel substrate gradually decreased with increasing substrate temperature. The critical wetting temperature of liquid Li on stainless steel was observed to be about 290 C.
