Abstract
The electrical resistivity of liquid Pb–Te alloys has been measured as a function of temrerature and concentration. The resistivity isotherm has a remarkable maximum and the temperature coefficient of the resistivity has large negative value around the equiatomic composition, suggesting that a kind of compound formation exists at this composition. The excess resistivities are interpreted interms of the resonance scattering caused by the compound of PbTe with a finite life time. A similar behaviour of the resistivity in liquid Sn–Te alloys is also explained satisfactorily by the same model.Keywords
