Melt viscosities in the system Na-Fe-Si-O-F-Cl: Contrasting effects of F and Cl in alkaline melts
Melt viscosities Na-Fe-Si-O-F-Cl alkaline melts
2012/4/1
The shear viscosities of melts in the system Na-Fe-Si-O-F-Cl were determined over a wide range of temperatures (400–1200 8 C) at 1 atm pressure in air. The compositions are based on the addition of Fe...
