摘要：
Interdiffusion in potassium-lead melts containing 30, 40, 50, 66.7, and 84.4 at. % Pb was investigated using gamma-ray attenuation technique in the temperature range from 550 to 970 K. It was found that the concentration dependence of interdiffusion coefficient has a maximum in the vicinity of 40-50 at. % Pb. It was shown that this feature is associated with the trend of forming ionic complexes of K4Pb4 in liquid alloys.
