HIGH-PURITY SILICON DIOXIDE GRANULES FOR QUARTZ GLASS APPLICATIONS AND METHOD FOR PRODUCING SAID GRANULES

It has been found that conventional cheap waterglass qualities in a strongly acidic medium react to give high-purity silica grades, the treatment of which with a base leads to products which can be processed further to give glass bodies with low silanol group contents.
