• A series of SiO2 glasses were synthesized by using spectroscopically pure silica on the YJ-3000 multi-anvil apparatus at 355–445°C and 2.0–5.5GPa. Their spectroscopic characteristics resemble that of the high-density quartz glass. In the meantime, the IR spectra of SiO2 glasses show that a small amount of water exists in SiO2 glasses in the form of OH-. It may be due simply to the small amount of water that contributes significantly to the amorphism of SiO2. The determination of refraction indices of SiO2 glasses shows that the refraction indices of SiO2 glasses and the high-density quartz glass are in good logarithmic relation with synthetic pressures.
