In situ Ca-F cluster formation during crystallisation of mold fluxes

Abstract: Mold fluxes are used as sort of ?lubricants? for molten steel, and are prepared as mixtures of calcite, flurite, some SiO2, and some Na: these mixtures are tailored to melt at certain temperature, providing a molten layer that works as a lubricant. These melts, at lower T, start to crystallise, forming a mineral called cuspidine and some other Ca-silicates. The very beginning of the process is the most interesting part, because what happens (likely the formation of Ca-F clusters) changes radically the rheological properties of the material, and therefore its ability to function as a lubricant. The idea behind this proposal is to first start the structure of these amorphous materials ex-situ, and then to study the onset of crystallisation from melt, looking for Ca-F clusters, which, if present and depending on their size, changes considerably the rheological properties of the material.
