Under such high temperature, the powder raw materials will decompose and react to produce the required products. This method generally uses WO3, WC or w as the w source and CH4 as the C source. After the reaction, it mainly produces \u03b2- The research of WC or W2C, Japan&#8217;s Kuriyama, etc. shows that when the molar ratio of CH4 to WC is greater than 15, \u03b2- The mass fraction of WC is 90%-95% and the particle size of the powder is about 10nm.

WC powder can be divided into ultra coarse tungsten carbide, micron tungsten carbide, sub micron tungsten carbide, sub nano tungsten carbide and nano tungsten carbide according to the particle size. In terms of application, submicron tungsten carbide powder is mainly used to produce cemented carbide, superhard cutting tools, jet engine parts and kiln structural parts. Properties of submicron tungsten carbide powder From the definition, tungsten carbide is a compound composed of transition metal&#8230;<\/p>","protected":false},"author":2,"featured_media":21210,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[79],"tags":[],"class_list":["post-21208","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-materials-weekly"],"jetpack_featured_media_url":"https:\/\/www.meetyoucarbide.com\/wp-content\/uploads\/2022\/06\/u21432709063201718835fm253fmtautoapp138fJPEG.webp","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/21208","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/comments?post=21208"}],"version-history":[{"count":0,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/21208\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media\/21210"}],"wp:attachment":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media?parent=21208"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/categories?post=21208"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/tags?post=21208"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
