Surface Tension during Molten Metal Granulation

The surface tensions of a number of common commercial ferroalloys have been measured during their granulation in water. These measured values are significantly lower than would be expected from a normal metal-gas interface and are more typical of the interfacial tensions of slag-gas interfaces. This would seem to indicate that the slag-metal interface on the surface of a granule produces no sig...

Molar Volume and Surface Tension of Molten LaCl3-KCl Mixtures

M olar volumes and surface tensions o f m olten L aC l3-KCl m ixtures were m easured by dilatom etry and the m axim um bubble pressure m ethod, respectively. The m olar volum e isotherm s were found to deviate positively from additiv ity over the whole com position range, with the m axim um deviation at ca. 30 mol% L aC l3. At the same concentration the isotherm s o f surface tension at tem per...

Surface Tension of Serum

An attempt was made to apply to the study of immune sera the fact, pointed out in our previous papers, that at a given dilution the serum shows a maximum drop of surface tension in function of time (time-drop). The results of the experiments here reported would seem to indicate that: 1. The time-drop of a serum solution is greater after the animal has been immunized than before immunization (fr...

Surface Tension of Serum

As stated in previous papers, 1-4 the four essential conditions under which the presence of antibodies in immune serum can be detected and followed by means of what might be termed the tensiometric method are: first, the dilution of the serum to 1:10,000; second, the use of strictly clean vessels; third, the care in handling the solutions, which must absolutely not be disturbed between the two ...
