Barium metaborate is also known as barium borate. White powder. Molecular weight 349.07. Dissolve in water. Functional pigments. It can enhance the anti- mildew, anti-rust, fire and anti-pulverization properties of the coating. It is prepared by adding barium sulfide and borax aqueous solution into the autoclave, adding a small amount of sodium silicate and heating at 125 ~ 140\u2103. At present, according to the data of different manufacturers, the particle size of barium metaborate commodity generally fluctuates in 0.35 ~ 35\u03bcm, the average particle size is about 8\u03bcm, and the effective particle size is only 3\u03bcm; The existing barium metaborate has the disadvantages of moisture absorption, caking, high water solubility, poor compatibility in various resins and poor firmness in paint film, so it must be modified with amorphous hydrated silica. At present, the existing method of preparing barium metaborate is to melt barium salt (barium sulfide, barium hydroxide, barium carbonate,\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-784","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\/784","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=784"}],"version-history":[{"count":5,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/784\/revisions"}],"predecessor-version":[{"id":1530,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/784\/revisions\/1530"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=784"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=784"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=784"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=784"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
