Based on experimental data on the surface tension (σ) of indium–tin–lead, thallium–lead–bismuth and indium–tin–gallium melts, the features of σ changes with composition changes were revealed. The boundary binary systems indium–tin and thallium–lead are characterized by the presence of a minimum on the σ isotherm of the melts. It is shown that in the studied ternary systems, the characteristic minimum on the σ isotherms along the sections of the triangle of compositions with a constant content of the third component is preserved.
