Cu-SeおよびCu-Te系合金の表面張力

抄録

The effects of dissolved Se and Te on the surface tension of liquid Cu have been measured by a sessile drop method at various temperatures. Se and Te are highly surface- active in liquid Cu, and the maximum surface excess of Se and Te were calculated to be about 1.4×10⁻⁹ mol·cm⁻² and 1.2×10⁻⁹ mol·cm⁻² respectively; these values correspond to mono-molecular layers of Se⁻⁻ or Te⁻⁻. These results are similar to the findings with Cu-S and Cu-O alloys reported in our previous paper.
