摘要: The phase compositions of high Ti bearing titanomagnetite sinter with different contents B2O3 were studied at 1623 K under an oxygen partial pressure 5×10−3 atm. results showed that mainly gathered in Ca2SiO4 and formed 2CaO.xSiO2.2/3(1−x)(B2O3) phase. appearance can restrain the precipitation CaTiO3 promote amount Fe mineral current experimental condition. In addition, shape changed from bulk to strip type increase content. formula silicoferrite calcium aluminium 1·6CaO.4·9Fe2O3.Al2O3.1·8SiO2 2·5CaO.5·9Fe2O3.Al2O3.2·6SiO2, dicalcium (boron) silicate 2CaO.SiO2 2CaO.0·33SiO4.0·45B2O3 when content was 0 2·0 mass-% sinter. change addition will be beneficial for improving its metallurgical properties.
