Summary

Dense, foam free, transparent gel-derived silica was produced using microwave energy (1600W). A processing schedule using microwave energy for 14 hours yielded a dense silica glass with high transmission (>93%) and an UV cut-off similar to that of fully dense gel-derived silica glass processed conventionally under chlorination. The dehydration process has not been completed under the processing conditions described in this study. More work is needed in order to improve on the dehydration process of samples irradiated with microwave energy.
