Study on Viscosity of the La2O3-SiO2-Al2O3 Slag System

Effect of MnO on High-Alumina Slag Viscosity and Corrosion Behavior of Refractory in Slags

“…It can be found that the viscosity of the slags gradually increases with the temperature decreasing and decreases with the addition of MnO. It is consistent with some previous studies, 10,11,17) 19) O − is the oxygen bonded to one silicon, which can formed according to the reaction (1). This transition could promote to simplify the slag structures and improve the fluidity of slag.…”

“…Kim et al 9) revealed the effect of MnO on viscosity and structure of TiO 2 -MnO-SiO 2 welding fluxes. Deng et al 10) found that the addition of MnO could reduce the viscosity of La 2 O 3 -SiO 2 -Al 2 O 3 slag. Zuo et al 11) investigated the viscosity of CaO-SiO 2 -MgO-Al 2 O 3 -MnO slag systems and the wetting behaviour between slag and refractory, the results showed that the slag viscosity decreased and…”

Effect of TiO₂ and MnO on Viscosity of Blast Furnace Slag and Thermodynamic Analysis

“…As can be seen in Fig. 4(a), the increase of MnO content lowers the viscosity of the slag, which is basically consistent with the previous studies, 8,[12][13][14]31) although the slag composition is somewhat different. Similar to the TiO 2 , the decrement in viscosity with increasing MnO content becomes more obvious at lower temperatures, where the amount of excess thermal energy may be not sufficient to thermally modify the network structures of the slag.…”

“…[34][35][36] Conse- -tetrahedral structure to some extent and reducing the viscosity of the slag. 8,12) Additionally, it can be seen from Fig. 4(b) that the critical temperature of the slag decreases as the MnO content increases.…”

“…At present, there have been some studies about the effect of TiO 2 or MnO on the properties of slags. [4][5][6][7][8] Work done by Shankar et al 9) and Park et al 10) found TiO 2 lowered the viscosity of titanium-bearing slags. Gao et al 11) studied the effect of TiO 2 on the CaO-SiO 2 -MgO-Al 2 O 3 -TiO 2 -B 2 O 3 slag system and found that the slag viscosity and break point temperature increased with increasing TiO 2 content.…”
