Quartz glass, commonly referred to as fused silica, is an amorphous material composed almost entirely of silicon dioxide (SiO\u2082). Unlike crystalline quartz, quartz glass does not possess a long-range ordered lattice structure. Instead, its atomic arrangement is typically described by the Continuous Random Network (CRN) model. In this structural model, silicon atoms are coordinated with […]<\/p>\n","protected":false},"author":1,"featured_media":2503,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[1],"tags":[524,522,523,521,511,529,530,526,528,532,520,75,531,527,525],"class_list":["post-2502","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-news","tag-cvd-quartz-glass","tag-electric-fusion-quartz-glass","tag-flame-fusion-silica","tag-fused-silica-manufacturing","tag-high-purity-quartz-glass","tag-hydroxyl-in-fused-silica","tag-optical-quartz-materials","tag-pcvd-silica-process","tag-quartz-glass-defects","tag-quartz-glass-optical-properties","tag-quartz-glass-preparation","tag-semiconductor-quartz-materials","tag-silicon-dioxide-glass-manufacturing","tag-sol-gel-silica-glass","tag-synthetic-fused-silica"],"_links":{"self":[{"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/posts\/2502","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/comments?post=2502"}],"version-history":[{"count":1,"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/posts\/2502\/revisions"}],"predecessor-version":[{"id":2504,"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/posts\/2502\/revisions\/2504"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/media\/2503"}],"wp:attachment":[{"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/media?parent=2502"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/categories?post=2502"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fuyao-quartz.com\/cs\/wp-json\/wp\/v2\/tags?post=2502"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
