Measuring and Modeling Viscosity of CaO-Al2O3-SiO2(-K2O) Melt
The effect of K2O on viscosity in CaO-SiO2-Al2O3 melt has been measured by a rotating spindle viscometer. It is indicated from the experimental results that viscosity first increases then decreases with the increasing content of K2O; the maximum viscosity occurs in the field of K2O/ Al2O3 > 1. After gradually adding K2O, the transformation of bridging oxygen (from being bonded with Al ion charg...
متن کاملStructural properties of molten silicates from ab initio molecular-dynamics simulations: comparison between CaO-Al2O3-SiO2 and SiO2
We present the results of first-principles molecular-dynamics simulations of molten silicates, based on the density functional formalism. In particular, the structural properties of a calcium aluminosilicate [ CaO-Al2O3-SiO2 ] melt are compared to those of a silica melt. The local structures of the two melts are in good agreement with the experimental understanding of these systems. In the calc...
متن کاملSynthesis of Nanoscale CaO-Al2O3-SiO2-H2O and Na2O-Al2O3-SiO2-H2O Using the Hydrothermal Method and Their Characterization
C-A-S-H (CaO-Al₂O₃-SiO₂-H₂O) and N-A-S-H (Na₂O-Al₂O₃-SiO₂-H₂O) have a wide range of chemical compositions and structures and are difficult to separate from alkali-activated materials. Therefore, it is difficult to analyze their microscopic properties directly. This paper reports research on the synthesis of C-A-S-H and N-A-S-H particles with an average particle size smaller than 300 nm by apply...
متن کاملdesulfurization of plain carbon steel by cao-al2o3-sio2 and cao-al2o3-sio2-x (x = na2o, sro) synthetic slags
synthetic slag process decreases sulfur and phosphorus contents of steel, improves inclusion removal, protects steel from atmosphere and prevents temperature drop of the liquid steel in the ladle. in this study, the synthetic slags of ternary cao-al2o3-sio2,and quaternary cao-al2o3-sio2-na2o and cao-al2o3-sio2-sro systems were pre-melted and then were kept in contact with the liquid steel in a ...
متن کاملThermodynamic simulation on mineralogical composition of CaO–SiO2–Al2O3–MgO quaternary slag system
It is necessary to elucidate the crystallization thermodynamic of mineralogical phases during the cooling process of the molten BFS with different chemical composition, because the high-melting point mineral phase maybe crystallized during the fiber forming and thereafter cooling process. Thermodynamic calculation software FactSage6.4 and the hot remelting experiments were performed to explore ...
