High-purity silicon dioxide granules for quartz glass applications and method for producing said granules

It has been found that conventional cheap waterglass reacts in a strongly acidic medium to form high-purity grades of silica whose treatment with a base leads to products which can be further processed into glassware having low silanol group contents. 已经发现，传统的廉价的水玻璃在强酸性介质中反应得到高纯度的二氧化硅等级，将其用碱处理而得到的产物...

More Information
Summary:It has been found that conventional cheap waterglass reacts in a strongly acidic medium to form high-purity grades of silica whose treatment with a base leads to products which can be further processed into glassware having low silanol group contents. 已经发现，传统的廉价的水玻璃在强酸性介质中反应得到高纯度的二氧化硅等级，将其用碱处理而得到的产物经进步处理可得到硅烷醇基含量低的玻璃体。
