                  Sapphire (Al\u2082O\u2083) is widely used in high-power laser systems, precision optics, deep-sea observation windows, and aerospace equipment due to its exceptional mechanical strength, high hardness, chemical stability, and broad optical transparency. Despite these superior properties, sapphire windows are not immune to cracking or fracture during operation. Cracks can compromise system performance and lead to costly […]<\/p>\n","protected":false},"author":1,"featured_media":2329,"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":"","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":[17],"tags":[526,524,520,527,525,523,220,521,528,507,522,62,264,187,54,517,519,360,518],"class_list":["post-2327","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-news","tag-aerospace-materials","tag-brittleness","tag-chemical-corrosion","tag-deep-sea-windows","tag-failure-modes","tag-finite-element-analysis","tag-high-power-lasers","tag-manufacturing-defects","tag-material-defects","tag-mechanical-stress","tag-microcracks","tag-optical-materials","tag-precision-optics","tag-sapphire","tag-sapphire-window","tag-stress-concentration","tag-thermal-shock","tag-thermal-stress","tag-window-cracking"],"_links":{"self":[{"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/posts\/2327","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/comments?post=2327"}],"version-history":[{"count":1,"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/posts\/2327\/revisions"}],"predecessor-version":[{"id":2330,"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/posts\/2327\/revisions\/2330"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/media\/2329"}],"wp:attachment":[{"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/media?parent=2327"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/categories?post=2327"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sapphire-windows.com\/vi\/wp-json\/wp\/v2\/tags?post=2327"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
