N2 - To investigate the effect of transition metal oxides on the evaporation characteristic of SiO2 glass at 1700°C, nine transition metal oxides were added to SiO2 glass. The results show that V2O5, MoO3, and WO3 have little effect on the high-temperature stability of SiO2 glass due to their evaporation at 1500-1700°C. Besides, Nb2O5 and Ta2O5 reduce the evaporation of SiO2 by covering the surface of the sample. Moreover, by improving the content of cristobalite, the evaporation of the SiO2-Cr2O3 sample decreases. Meanwhile, TiO2, ZrO2, and HfO2 are beneficial to decreasing the evaporation of SiO2 glass because Ti, Zr, and Hf diffuse into c-SiO2. Meanwhile, the SiO2-HfO2 sample possesses the least evaporation.
