Abstract
A process for forming monolithic silica glass articles is provided. The process includes the steps of hydrolyzing silicon alkoxide to form a hydrolyzed solution, adding fumed silica to the hydrolyzed silicon alkoxide solution to yield a sol solution, gelling the sol solution to a gel, and drying and sintering the gel to obtain the monolithic silica glass articles.
