The viscosity of low SiO 2 (10–20 mass%)-CaO-Al 2 O 3 slag system was measured in a wide temperature range (1623–2800 K) using the rotational bob method and the aerodynamic levitation method. The influence of SiO 2 /Al 2 O 3 ratio and CaO/Al 2 O 3 ratio on the viscosity was examined. It was concluded that the SiO 2 /Al 2 O 3 ratio did not affect the degree of polymerization of the ...
