Preparation of quartz glass tube

Abstract

Abstract PURPOSE:To obtain a high-quality quartz glass tube inexpensively, by gelatinizing a silica sol-containing solution with rotating it in a rotator, followed by evaporation, drying, and sintering. CONSTITUTION:Fine powder of silicic acid or alkylsilicate is hydrolyzed. This sol solution 6 is packed into the proper tube 5, and the tube 5 is rotated, to give hollow gel. It is dried by evaporation, to give dried gel, which is sintered and made into glass. Quartz glass is obtained at low temperature by this method. A quartz glass tube having inner surface close to mirror surface and no foam left in the interior can be prepared.
