Verusil is a transparent, synthetic fused silica. It is manufactured solely from synthetic raw materials using a special Sol-Gel process.<\/p>

It is characterized by its high chemical purity. Verusil typically has an OH-Content of approx. 300 ppm and is mainly used in optical<\/a> (non-imaging), analytical<\/a> and technical<\/a> applications.<\/p>

By applying a special subsequent purification step, the purity of Verusil can be further increased on request and the content of OH groups can be reduced to almost zero.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Verusil Verusil is a transparent, synthetic fused silica. It is manufactured solely from synthetic raw materials using a special Sol-Gel process. It is characterized by its high chemical purity. Verusil typically has an OH-Content of approx. 300 ppm and is mainly used in optical (non-imaging), analytical and technical applications. By applying a special subsequent purification […]<\/p>\n","protected":false},"author":5,"featured_media":0,"parent":3973,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-3978","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/pages\/3978","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/comments?post=3978"}],"version-history":[{"count":5,"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/pages\/3978\/revisions"}],"predecessor-version":[{"id":4915,"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/pages\/3978\/revisions\/4915"}],"up":[{"embeddable":true,"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/pages\/3973"}],"wp:attachment":[{"href":"https:\/\/www.iqs.glass\/en\/wp-json\/wp\/v2\/media?parent=3978"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
