Viscosity and structure of iron- and aluminum-bearing calcium silicate melts at 1 atm

The temperature viscosity relationships of melts in the system CaO-SiO2-Fe-O have been determined and their values compared with those of similar melt composition with Al3+ rather than Fe3+ in substitution for Si4+. The viscosities of Fe-bearing melts range 5-15 poise at superliquidus T, and their a...

Summary:The temperature viscosity relationships of melts in the system CaO-SiO2-Fe-O have been determined and their values compared with those of similar melt composition with Al3+ rather than Fe3+ in substitution for Si4+. The viscosities of Fe-bearing melts range 5-15 poise at superliquidus T, and their activation energies of viscous flow between 8 and 50 kcal/mol. as a function of Ca/Si, Fe content and temperature (in the range 1400-1600°C).
