Viscosity model for oxide melts relevant to fuel slags. Part 2: The system SiO 2 –Al 2 O 3 –CaO–MgO–Na 2 O–K 2 O

“…29 shows, the substitution of SiO 2 for Al 2 O 3 leads to varying viscosity maxima for different slags at 1300°C. The viscosities [84,89] of the slag 10, slag 11 and slag 12 are satisfactorily reproduced. It is found that the substitution of CaO for Na 2 O causes a right shift in position of the viscosity maximum at constant contents of MgO and K 2 O.…”

“…28 shows, the current model allows a satisfying performance in reproducing the experimental data [83][84][85]. It is seen that the viscosity of three slags follows the order: slag 9 N slag 7 N slag 8, which is reasonable when the charge compensation effect is taken into account.…”
