Obtaining transparent silica glass from nano-silica hydrosol

Transparent silica glass is widely used in various fields. However, a simple and economical method of synthesis remains to be developed for high-precision device manufacturing. In this study, transparent silica glass is fabricated from low-cost commercial nano-silica hydrosol. To obtain transparent glass, the crystallization temperature of bulk materials must be higher than their densification temperature. Based on XRD analysis, impurity ions...
