CAS: 13701-59-2 Barium metaborate B2BaO4, molecular weight 222.95, white rhombic crystalline crystalline powder. Relative density 3.25 ~ 3.35. Melting point 1060\u2103. Slightly soluble in water, easily soluble in hydrochloric acid. It has the properties of rust prevention, powder resistance, high temperature resistance, fire prevention and mildew prevention. Modified barium metaborate is a new non-toxic anti-rust pigment used in primer and topcoat in coating industry, and is also used in ceramics, papermaking, rubber, textiles and plastics industries. Synthesis method: 1, borax barium sulfide method (usually) : \u2460 The mixture of barite and pulverized coal is calcined, leach with hot water in the extractor, and the barium sulfide liquid is obtained, and then the borax aqueous solution and sodium silicate aqueous solution are separately added to the reactor. After adding the three kinds of materials, the reactor is closed, the temperature is raised to 110\u2103\u00b15\u2103, and the reaction is stirred for 2\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[29],"attr":[],"class_list":["post-794","post","type-post","status-publish","format-standard","hentry","category-problems","tag-barium-metaborate"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/794","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=794"}],"version-history":[{"count":4,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/794\/revisions"}],"predecessor-version":[{"id":1533,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/794\/revisions\/1533"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=794"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=794"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=794"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=794"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
