Abstract

PURPOSE:To facilitate the production of a doped quartz glass of homogeneity and a large shape, by dispersing fine particles of silica in an alkyl silicate hydrolyzate, forming sol, after its pH is adjusted, then drying and heating the sol. CONSTITUTION:Alkyl silicate is hydrolyzed using an acidic catalyst, fine particles of silica are dispersed in the hydrolyzate, and the silica dispersion is adjusted in its pH to 3-6. Then, dopants containing at least one elements or dopant solutions are added to the silica dispersion to form a sol. The sol is converted into the gel, the gel is dried, and the dry gel is heated into a glass. The dopants are selected according to the purposes for the doped quartz glass, and the process according to the present invention can use any element substances as a dope.
