Barium is an extraordinarily reactive metal that is so prone to oxidation that the property is actively exploited wherever oxygen (and other gases) are unwanted. This happens, for example, in devices which need to hold a vacuum. Rather than employ costly measures to avoid trapping all traces of contaminants it is often simpler - and equally effective - to place a small amount of barium in the vacuum where it will hungrily 'mop up' those undesirable elements.\u003c\/p\u003e\u003cp style=\"white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eWhile barium is a gray metal it is essentially a hopeless cause for the collector to retain a sizable amount of the metal in its unoxidized state precisely because of the difficulty of first eliminating every last trace of non-inert material from a container and then, if this much can be achieved, keep it sealed so well that nothing gets in. Realistically, it can only be done by sealing in sturdy glass with a noble gas. Even so, the metal reacts with nitrogen which is found in trace amounts in these noble gases.\u003c\/p\u003e\u003cp style=\"white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eTo guarantee that this very fragile metal does not degrade these cubes have been enclosed in glass ampules under argon gas.\u003c\/p\u003e\u003cp style=\"white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003e10mm cube weight is approximately 3.5 grams.\u003c\/p\u003e","brand":"Luciteria","offers":[{"title":"10mm sealed glass cube 0.1g crystals","offer_id":47820853739685,"sku":"Ba10mm_sg","price":20.0,"currency_code":"USD","in_stock":true},{"title":"10mm cube in 18x60mm flat bottom ampule","offer_id":47820853772453,"sku":"Ba10mm","price":279.25,"currency_code":"USD","in_stock":true},{"title":"25.4mm in glass dome","offer_id":47820853805221,"sku":"Ba25.4mm_dome","price":1250.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/8833\/6805\/files\/Barium_283_29.webp?v=1778165612","url":"https:\/\/luciteria.com\/products\/barium-metal-cube-99-9","provider":"Luciteria","version":"1.0","type":"link"}
