Density and Compressibility of Liquid Li-Pb Alloys

Abstract

The density and the velocity of sound of liquid Li-Pb alloys have been measured in the composition ranges 0 -17, 30 -100 at % Pb and 0-10, 40 -100 at % Pb, respectively. The temperature dependence of these properties has been determined for each sample in a temperature range of at least 130 K. The excess volume is negative and has a minimum at about 20at%Pb, where the volume per atom at 800 °C is about 19% smaller than the volume of an ideal solution. The absolute value of the excess volume rises with the temperature, as does the absolute value of the deviation of the adiabatic compressibility from the mean compressibility.

Thermodynamic, surface and structural properties of liquid Co-Si alloys

“…16 the bonding character of the liquid melts and compressibility curves together with a number of other thermophysical properties exhibit irregularities near the composition of an energetically favoured intermetallic compound and thus substantiate the presence of short-range ordering in the melt, as it was experimentally confirmed by diffraction experiments for liquid Li-Pb alloys [60]. The curves describing the molar volume (Fig.…”

“…3a) as well as the adiabatic and the isothermal compressibility (Fig. 3b) of liquid Co-Si alloys have similar trends as those observed in the Li-Pb [31,60].…”

Influence of Zinc on the Surface Tension, Density and Molar Volume of (Ag-Sn)eut +Zn Liquid Alloys

“…Such behavior was observed, for example, in solid Al-Li, Li-Mg and Al-Li-Mg alloys [29,30,31] and Li-Mg or Li-Pb [ 32,33] or in the case of many other binary liquid alloys with alkaline metals [34] which possess negative deviations from the ideal solutions, as well as in the case of the Pb-Sn system [1] with positive deviations. fig.…”

Studies on Thermophysical Properties of CaO and MgO by γ-Ray Attenuation

“…In general the thermal expansion characteristics decide the choice of material for the construction of metrological instruments and the choice of container material in nuclear fuel technology. A number of methods have evolved for the determination of density and thermal expansion of solids at high temperature like Archimedean method [1][2][3], pycnometry [4][5][6][7][8], dilatometry [9][10][11][12], electromagnetic levitation [13], method of maximal pressure in gas bubble [14][15][16][17][18], method of sessile drop [19], hydrostatic weighing [20,21], high temperature electrostatic levitation [22], and gamma ray densitometry [23][24][25][26][27][28][29][30][31][32][33][34]. Using -ray attenuation technique Drotning [23] measured thermal expansion of solid materials at high temperatures.…”
