Surface tension and adsorption of lithium in bismuth-based alloys

详细

Temperature and concentration dependences of the surface tension of 11 alloys of the Bi–Li system in the interval of compositions with up to 10.46 at % Li content are determined for the first time. A shallow sloping minimum is observed on the surface tension isotherm in the region with small lithium additives in bismuth. Lithium adsorption with liquid bismuth is calculated with the obtained data. It is shown that the maximum value of lithium adsorption is obtained with compositions with 0.8 at % Li content, and the adsorption isotherm has its minimum value in alloys with about 4 at % Li content.
