Abstract

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.
