Density of the Blast Furnace Slag Bearing TiO 2 at 1673 K

The density of blast furnace slag bearing TiO 2 has been investigated using the dispensed drop method at 1673 K under the Argon atmosphere (Pressure ≈ atm). The influence of slag basicity and the TiO 2 content on the density was analyzed according to the measurements. It was found that the density of the slag increases with increasing the TiO 2 content from 0% to 23%, once the TiO 2 ...
