Structure and electrical properties of liquid Sn, Sn0.962Ag0.038, Sn0.987Cu0.013, and Sn0.949Ag0.038Cu0.013


We have studied the structure, electrical conductivity, and thermopower of liquid Sn, Sn0.962Ag0.038, Sn0.987Cu0.013, and Sn0.949Ag0.038Cu0.013 alloys, which are used as lead-free solders. Diffraction data have been used to develop structural models of the melts. The conductivity and thermopower data have been interpreted in terms of the proposed structural models and resonance s-d scattering.
