YouTube vlogger thunderf00t has performed this preparation, as it seems to be much cheaper to perform this extraction than it is to buy the metal (but it is far more convenient to just buy the metal). One way is to reduce caesium halides with a reactive metal such as calcium, barium, or lithium at 700-800 ☌, followed by distillation of the caesium metal. Ĭesium compounds, such as cesium formate, are used as drilling fluids.īecause it's extremely reactive, isolating pure caesium metal is extremely difficult. The exact composition of the alloy varies, depending on the generation of tube, as not all of them have cesium. Very small amounts of cesium alloys are used in the cathode of the electron gun from the cathode ray tube TVs. Another seller, SmartElements sells cesium ampoules cheaper, a 10 g ampoule is 179 € while a 1 g ampoule is only 79 €. It will react with water even at temperatures as low as −116 ☌.Ĭesium ampoules can be purchased from GalliumSource, however it is extremely expensive, a 100 g ampoule is 2400 $ and a small 1 g one is 140 $. It is the least electronegative element and is extremely reactive and even pyrophoric. It has a very low melting point of 28 ☌, meaning it can be a liquid at near room temperature or if held in one's hand. HNO 3 and CsNO 3♲HNO 3Ĭaesium hydroxide is extremely corrosive and attack glass much faster than the other alkali hydroxides.Ĭaesium is a soft alkali metal, silvery-gold in color.The reaction with water is explosive, capable of shattering the water's glass container.Ĭaesium also forms two unusual acid nitrates, CsNO 3 Caesium is an extremely reactive metal an will spontaneously ignite in air to form caesium oxides and hydroxides.
