This comes from a manufacturing process that makes use of extreme heat to create exceptional performance characteristics. This high-performance ceramic material undergoes a recrystallization process at temperatures between 2200\u00b0C and 2500\u00b0C and transforms into a material capable of withstanding operational temperatures […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[30],"tags":[],"class_list":["post-678","post","type-post","status-publish","format-standard","hentry","category-sic-knowledge"],"aioseo_notices":[],"_links":{"self":[{"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/posts\/678","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/comments?post=678"}],"version-history":[{"count":2,"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/posts\/678\/revisions"}],"predecessor-version":[{"id":680,"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/posts\/678\/revisions\/680"}],"wp:attachment":[{"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/media?parent=678"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/categories?post=678"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/siliconcarbide.net\/az\/wp-json\/wp\/v2\/tags?post=678"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
