Abstract

A fast process for producing pure silica glasses with the reproducibility of 100% by means of sintering of silica aerogels was optimized. The density of silica glasses synthesized by heat-treating upto 110$0^{\circ}C$ with the heating rate of 0.1$^{\circ}C$/min was 2.197 g/㎤. Synthetic silica glasses(5 mm thickness) exhibited the transmittance of 92% in the near IR range as well as they had the excellent mechanical properties such as flexural strength of 162 MPa and hardness of 778 kg/$\textrm{mm}^2$.
