From viscosity and surface tension to Marangoni flow in melts*

From: Metallurgical and Materials Transactions | Date: October 1, 2003| Author: | Copyright information

This article covers some of our recent work on slag viscosity, the surface tension of liquid Cu-O alloys, and the relative role of Marangoni and bulk flow on refractory wear in iron-silicate slags. A viscosity model developed for slags containing SiO^sub 2^, Al^sub 2^O^sub 3^, Fe^sub 2^O^sub 3^, CaO, MgO, MnO, FeO, PbO, NiO, Cu^sub 2^O, ZnO, CoO, and TiO^sub 2^ is capable of representing the effects of temperature, silica, and network-modifier cations within a wide range of temperatures and compositions. It forms a useful part of a computational package for multiphase-equilibrium (MPE) ...
