ABSTRACT:
A silica glass monolith fabricating method using a sol-gel process. In the method, a first sol is formed by mixing 100 parts by weight of high-density silica containing powder with 100-300 parts by weight of water, and rapidly dried, while the pH of the first sol is being controlled in the range between 9 and 11. The dried first sol is powdered and then thermally treated at or above 600.degree. C., and a second sol is formed by mixing the thermally-treated powdered first sol with 100-200 parts by weight of deionized water and a aqueous organic binder. The second sol is gelled in a mold, dried, thermally treated, and sintered. Thus, a high-purity silica glass monolith is obtained.
