VISCOSITY OF СaО – SiO2 – Al2O3 – MgO – B2O3 SLAG SYSTEM

Thermodynamic 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 ...

Kinetics of spinel formation and growth during dissolution of MgO in CaO-Al2O3-SiO2 slag

Intrinsic viscosity of SiO2, Al2O3 and TiO2 aqueous suspensions.

The viscosity of dilute suspensions of several metal oxides (SiO2, Al2O3 and TiO2) was measured at different pH values. The intrinsic viscosity, [eta], was derived from the concentration dependence of the viscosity. This magnitude was pH-dependent. A correlation with the shape of the kinetic unity has been proposed.

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...
