- The influence of B2O3 on the viscosity of high Ti-bearing BF slag is studied under Ar atmosphere from 1 773 K (1 500 degrees C) to about 1 593 K (1 320 degrees C). The results show that the addition of B2O3 can decrease the viscosity of high Ti-bearing BF Slag containing UPC, consequently improve its fluidity. With the existence of 1.5% UPC, when the content of B2O3 increased from 0 to 4.1%, the volume fraction of perovskite decreased from 7.7% to 1.6% at 1 610 K. Meanwhile, the liquidus temperatures decreased from 1 619 K to 1 613 K. At a lower temperature, B2O3 was easy to form a eutectic and decreased the viscosity of molten slag. At a higher temperature, some tetrahedron [BO4](5-) changed into triangle [BO3](3-) which would disintegrate the chains/molecules of molten matrix and decreased its viscosity.
