Abstract: | (δp/δT)s which is proportional to the specific heat has been measured between the liquidus temperature and 1250 K for the whole concentration range of liquid Li/Pb alloys. For all concentrations it shows a positive deviation from the values expected for an ideal solution and it exhibits a narrow peak close to the composition Li4Pb. The variation of T(δp/δT)s with T is linear only for pure Pb. At 0.2 < xLi < 0.6 a fall-off after melting is followed by a broad maximum at about 1000 K. |
