Few cesium mineral are know, pollucite is the main: they are silicate magmas cooled from granites. Cesium is used in atomic clocks and more recently in ion propulsion systems.Īlthough cesium is much less abundant than the other alkali metals, it is still more common than elements like arsenic, iodine and uranium. The chloride is used in photoelectric cells, in optical instruments, and in increasing the sensitivity of electron tubes. Cesium salts are used to strenght various types of glass. Cesium is sometimes used to remove traces of oxygen from the vacuum tubes and from light bulbs. Cesium nitrate is used to make optical glasses. Cesium metal oxidized rapidly when exposed to the air and can form the dangerous superoxide on its surface.Ĭesium is used in industry as a catalyst promoter, boosting the performance of other metal oxides in the capacity and for the hydrogenation of organic compounds. Cesium reacts with the halogens to form a fluoride, chloride, bromide, and iodide. Cesium hydroxide is a strong base and attacks glass. Cesium reacts explosively with cold water, and reacts with ice at temperatures above -116☌. Cesium, gallium, and mercury are the only three metals that are liquid at or around room temperature.
It is the most electropositive and most alkaline element. The metal is characterised by a spectrum containing two bright lines in the blue (accounting for its name).
