Made of metallic and glassy oxygen-containing compounds, lava is heat-tolerant and fluid. To mimic these properties, chemist Pingan Song from the University of Southern Queensland, Australia, and his colleagues mixed powdered metal oxides with boron nitride, a heat-resistant compound. They then added a fire-retardant polymer. The oxides melt at low temperatures\u2014around 350 degrees Celsius (\u00baC), less than the heat of the flames\u2014and form a kind of glass film. As the glass forms, the boron nitride fits into the spaces between the oxides and increases the material&#8217;s heat resistance. The fire-retardant polymer acts as a glue, helping the mixture adhere to different materials. When sprayed on a block of foam, a piece of wood, and a steel blade, it prevented them from burning even after 30 seconds of exposure to a 1,100 \u00baC blowtorch flame (<em>photograph<\/em>) (<em>Matter<\/em>, January 6).<\/p>\n","protected":false},"excerpt":{"rendered":"A group of researchers from China and Australia has developed a promising fire-retardant coating inspired by the properties of lava","protected":false},"author":475,"featured_media":423403,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[259],"coauthors":[785],"class_list":["post-431652","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-chemistry"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/431652","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=431652"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/431652\/revisions"}],"predecessor-version":[{"id":431653,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/431652\/revisions\/431653"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/423403"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=431652"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=431652"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=431652"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=431652"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
