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...

Surface Chemistry of Silica-Titania-supported Chromium Oxide Catalysts

The interaction of chromium oxide with different titania-silica supports has been examined. The oxide supports investigated consisted of SiO,, TiO, , physical mixtures of TiO, and SiO,, a surface titania overlayer on SiO, (10% of theoretical monolayer) and a surface silica overlayer on TiO, (80% of theoretical monolayer). The supported chromium oxide catalysts were structurally characterized wi...

Network structure of Mo-oxide glasses

The structure of molybdate glasses have been investigated by neutron and highenergy X-ray diffraction coupled with Reverse Monte Carlo (RMC) simulation technique. From the modelling the partial atomic correlation functions gij(r), the coordination number distributions CNij and bond angle distributions have been revealed. For binary 90MoO310Nd2O3 glass composition the fraction of MoO4/MoO6 was 0...

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...
