cesium usage and synthesis
chemical properties silvery, light ductile metal
general description a soft metallic solid. melts at 85°f. causes burns to skin and eyes.
air & water reactions highly flammable. cesium is spontaneously flammable in air at room temperature, if the surface is clean [merck 11th ed. 1989]. reacts with water to generate enough heat to ignite the hydrogen produced during the reaction, and to generate caustic cesium hydroxide [mellor 2 419 1946-47].
reactivity profile cesium metal reacts violently with oxidizing agents, even weaker ones. reacts with boron trifluoride with incandescence when heated [merck 11th ed. 1989]. reacts explosively with maleic anhydride [chem safety data sheet sd-88 1962; chem. haz. info. series c-71 1960]. burns in chlorine with a luminous flame [mellor 2 supp. 1:380 1956]. reacts violently with most acids. reacts violently with fluorine, chlorine, bromine and iodine. reacts with incandescence with sulfur and phosphorus. burns vigorously in air.
health hazard inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. may produce corrosive solutions on contact with water. fire will produce irritating, corrosive and/or toxic gases. runoff from fire control may cause pollution.
fire hazard produce flammable gases on contact with water. may ignite on contact with water or moist air. some react vigorously or explosively on contact with water. may be ignited by heat, sparks or flames. may re-ignite after fire is extinguished. some are transported in highly flammable liquids. runoff may create fire or explosion hazard.
