【発明の詳細な説明】
〔産業上の利用分野〕
本発明は耐熱性、耐薬品性のすぐれた着色石英ガラスの
製造方法、特に大型の着色石英ガラス体を製造するに適
した方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing colored quartz glass having excellent heat resistance and chemical resistance, and particularly to a method suitable for producing large-sized colored quartz glass bodies.
着色石英ガラスの製造方法として、従来、米国コーニン
グ社の開発した、気相中で四塩化珪素を酸素で分解して
多孔質シリカを作り.これに遷移金属塩の溶液を含浸さ
せ、高温で焼或する方法があって、米国窯業協会誌,第
57巻.第309〜313ページに記載されている。The conventional method for manufacturing colored quartz glass was developed by Corning Corporation in the United States, in which silicon tetrachloride is decomposed with oxygen in the gas phase to create porous silica. There is a method of impregnating this with a solution of a transition metal salt and firing it at high temperature, as described in Journal of the American Ceramics Association, Vol. 57. It is described on pages 309-313.
また珪酸エチル、エタノール、水の混合液に、遷移金属
塩を溶解し(遷移金属はイオン状態となる)、液のpH
を3ないし6として加水分解し、ゲル化させた後、高温
に加熱しガラス化させる方法があり、特開昭57−11
845に記載されている。In addition, a transition metal salt is dissolved in a mixture of ethyl silicate, ethanol, and water (the transition metal is in an ionic state), and the pH of the solution is
There is a method of hydrolyzing 3 to 6, gelling it, and then heating it to a high temperature to vitrify it.
845.
しかし上記のコーニング社開発の方法は、気相反応を必
要とし、一定量を製造するのに多くの時間を要するので
、原価が高くなる。However, the method developed by Corning Inc. requires a gas phase reaction and takes a long time to produce a certain amount, resulting in high cost.
一方、特開昭57−11845の方法は液相での反応を
用いているが、酸性媒体中での加水分解のため、得られ
るゲルを高温で加熱処理する際に発泡や割れが起こり易
く、大型の着色ガラス体を作ることが困難であった。On the other hand, the method of JP-A-57-11845 uses reaction in a liquid phase, but because of hydrolysis in an acidic medium, foaming and cracking are likely to occur when the resulting gel is heated at high temperatures. It was difficult to make large colored glass bodies.
それ故、本発明の目的は、液相での反応を利用して、安
い原価で、製造時の発泡や割れを生ずることなく大型の
着色ガラス体を作ることが可能な、着色石英ガラスの製
造方法を提供することである。Therefore, an object of the present invention is to produce colored quartz glass, which can produce large colored glass bodies at low cost and without foaming or cracking during production, by utilizing reactions in the liquid phase. The purpose is to provide a method.
上記目的を解決するため、本発明では着色石英ガラスの
