AbstractThis paper describes a part of the work performed on the determination of the thermophysical properties of alloys in the binary system LiPb. The preparation of the eutectic alloy from the pure elements and its characterization using chemical analysis, metallography, thermal and thermal differential analysis is described. Results of the measurements of the following properties are presented: latent heat of fusion, specific heat, density, thermal expansion, thermal and electric conductivity and viscosity. The wetting behaviour of Li(17)Pb(83) against SS 316 is discussed in terms showing the influence of especially of oxygen on the wetting angle in this system.
