る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing quartz glass products, and more particularly, for hydrolyzing alkyl silicate, the inner - is removed before the non-silicic acid gel obtained from K shrinks. Extraction-1: After that, KWK drying and firing method for producing quartz glass products were carried out.
近年、石英ガラス製品がその耐熱性、耐薬品性高純度郷
の性質故に多く用いられている。そして又、需要も年々
増加の傾向にある。In recent years, quartz glass products have been widely used due to their heat resistance, chemical resistance, and high purity properties. Furthermore, demand is also increasing year by year.

となる欠点がある。Silica glass with such excellent properties is currently manufactured by a melting method. In this melting method, natural quartz or high-purity silica sand is used as the raw material, and it undergoes a complex processing process of washing with water, sorting, hydrofluoric acid treatment, potting, and crushing.
It has the disadvantage of being expensive because it requires melting at a high temperature of about 0°C and a very long process 11.

A method called the sol-gel method, which allows silica glass to melt at low temperatures of around 0.9°C, is attracting a lot of attention.

本発明の目的はゾル−ゲル法を用い、今まで出来なかり
土管状の石英ガラス製品を柳供するためになされたもの
である。The object of the present invention is to use the sol-gel method to produce clay tube-shaped quartz glass products, which have not been possible until now.
従来の管状の石英ガラスを得る方法を[1図を参照しな
がら鰐明する。The conventional method for obtaining tubular quartz glass will be explained below with reference to Figure 1.

燥ゲルが収縮すると所、内−の型にシζえられ、割れて
しまい成形体を得ることは困薯でありた。The conventional method is to hydrolyze alkyl silicate, fill it with silica gel, and dry it to obtain a dry gel, which is then fired and fired to obtain a quartz glass tube. It was a method. However, in this method, when the dried gel contracts, it is squeezed into the inner mold and cracks, making it difficult to obtain a molded product.

−の型をぬぎとる。The manufacturing method of the present invention replaces such gaps in the method of Example 4E by using the same packaging as copper 1, and filling the same strands with the hydrolyzate. If you leave it alone for a while, assimilation will begin. The mold inside the mold is removed at an appropriate time when the mold has not started shrinking.
