Abstract

A silica glass fabrication method. The method includes the steps of adding silica and a dispersant to a premix solution obtained by dissolving a monomer for acrylic resin and a cross-linking agent in a distilled water, and dispersing themixed solution, and adjusting the pH of the mixture, to form a sol; removing airbubbles from the sol, and then aging the sol; adding a polymerization initiator to the aging-treated sol, and adjusting the pH of the reaction mixture; pouring thereaction mixture into a mold, aging the mixture in an incubator at a high temperature and then gelating the resultant; aging the obtained gel, demolding the aging-treated gel, and then drying the demolded gel; thermally-treating the dried gel to remove organic substances from the gel; and performing a hydroxy group elimination reaction and a sintering reaction on the gel from which organic substances have been removed. Therefore, a high purity silica glass tube, in which cracking after drying scarcely occurs and shrinking ratio is markedly low, can be obtained. Also, a large silica glass tube can be manufactured by this fabrication method.
