Abstract

The phase compositions of high Ti bearing titanomagnetite sinter with different contents of B₂O₃ were studied at 1623 K under an oxygen partial pressure of 561023 atm. The results showed that B ₂O₃ mainly gathered in Ca2SiO4 phase and formed 2CaO.xSiO₂.2/3(12x)(B₂O₃) phase. The appearance of B₂O₃ can restrain the precipitation of CaTiO ₃ and 2CaO.xSiO₂.2/3(12x)(B₂O₃) and promote the amount of Fe bearing mineral phase in the current experimental condition. In addition, the shape of CaTiO₃ changed from bulk to strip type with the increase in B₂O₃ content. The formula of silicoferrite of calcium and aluminium changed from 1.6CaO.4.9Fe2O ₃.Al₂O₃.1.8SiO₂ to 2.5CaO.5.9Fe2O₃.Al₂O₃.2.6SiO₂, and the formula of dicalcium (boron) silicate changed from 2CaO.SiO₂ to 2CaO.0.33SiO4.0.45B₂O₃ when B₂O₃ content was from 0 to 2.0 mass-% in the sinter. The change of phase compositions with the addition of B₂O₃ in the sinter will be beneficial for improving its metallurgical properties
