Abstract
The shape of the liquid-liquid coexistence curve of the Pb-Cu system with a miscibility gap has been determined by the γ-ray attenuation technique. According to the authors’ measurements, the coordinates of the critical point are T C=1253.7±1.5K, X C=37.2±0.3 at.% Pb. the critical exponent β of the coexistence curve equals 0.315±0.005, which agrees closely with the nonclassical value. Near the critical point the values (X 1+X 2)/2 (X 1 and X 2 are the concentrations of the phases in equilibrium with each other) exhibit a departure from the law of the rectilinear diameter.
