- Abstract
The tensile strengths of liquid sodium, lead and bismuth, possible coolant materials for generation-IV nuclear reactors, at 0 K (i.e., ideal tensile strength), 293 K, normal melting point and normal boiling point are determined based on generalized van der Waals equations of state. The parameters of the generalized van der Waals equations of state have been determined though the vapor–liquid critical-point parameters. The tensile strengths of liquid sodium, lead and bismuth at 0 K are found to be about 2.65 GPa, 4.67 GPa and 4.33 GPa, respectively. The tensile strengths of liquid sodium, lead and bismuth at 293 K are found to be about 1.33 GPa, 2.98 GPa and 2.62 GPa, respectively. The tensile strengths of liquid sodium, lead and bismuth at normal melting point are found to be about 1.20 GPa, 2.34 GPa and 2.36 GPa, respectively. The tensile strengths of liquid sodium, lead and bismuth at normal boiling point are found to be about 0.43 GPa, 0.90 GPa and 0.62 GPa, respectively. The tensile strengths of liquid lead at 0 K and 293 K, obtained in this work, satisfactorily agree with the literature data. Moreover, spinodal-pressure correlations for sodium, lead and bismuth have been formulated. These correlations are characterized by the correlation coefficient of about 0.9999 and the coefficient of determination of about 0.9999.
