The melting point of the glass increases with Strontium content. This glass makes seals with low melting metals like aluminium (melting point 650 \u00b0C). Normal borosilicate glasses soften above the melting point of aluminium. This mixture is prepared by heating a mixture of diammonium phosphate, sodium carbonate, and Strontium carbonate.<sup id=\"cite_ref-6\" class=\"reference\"><\/sup><\/p>","protected":false},"excerpt":{"rendered":"<p>100g &#8211; 250g &#8211; 500g- 1000g<\/p>","protected":false},"featured_media":48486,"template":"","meta":{"_acf_changed":false,"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":"default","ast-page-background-enabled":"default","ast-page-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":"","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-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":"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":""},"mobile":{"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":""}}},"product_brand":[],"product_cat":[49,364,125],"product_tag":[],"class_list":{"0":"post-5705","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-compounds","7":"product_cat-other-compounds","8":"product_cat-sr","9":"desktop-align-left","10":"tablet-align-left","11":"mobile-align-left","12":"ast-product-gallery-layout-horizontal-slider","13":"ast-product-gallery-with-no-image","14":"ast-product-single-variable","15":"ast-product-tabs-layout-horizontal","16":"ast-qv-on-image","18":"first","19":"instock","20":"taxable","21":"shipping-taxable","22":"purchasable","23":"product-type-variable"},"acf":[],"_links":{"self":[{"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/product\/5705","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":0,"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/product\/5705\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/media\/48486"}],"wp:attachment":[{"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/media?parent=5705"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/product_brand?post=5705"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/product_cat?post=5705"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/smart-elements.com\/de\/wp-json\/wp\/v2\/product_tag?post=5705"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
