Abstract: The effects of titania and the complex oxide as nucleation agents on the efficiency of boron extraction(EBE) from MgO-B2O3-SiO2 slags were investigated by means of chemical analysis, polarization microscope and X-ray diffraction (XRD).The results showed that titania promoted the glass phase separation, thus increasing the crystallinity, therefore, the EBE were obviously improved.The complex oxide as nucleation agent had more remarkable effect than titania, Moreover, the lower the EBE was before addition of nucleation agents,the higher the EBE was in creased after addition.
