Method of preparing silica glass

摘要

A method for preparing high quality silica glass articles is provided. The glass is prepared by hydrolyzing silicon alkoxide with a basic reagent to yield a first solution, hydrolyzing a silicon alkoxide with an acid reagent to yield a second solution, mixing the first solution with the second solution at a predetermined mixing rate to yield a sol solution, pouring the sol solution into a container, gelling the sol solution to a wet gel, drying the wet gel to a dry gel, and sintering the dry gel to yield a silica glass.
