rubidium usage and synthesis |
|
general description |
a soft silvery metal. shipped in very limited quantities sealed in a copper tube and over packed in a wooden box. used in electronics. |
|
air & water reactions |
tarnishes rapidly upon exposure to air. reacts violently with water to form corrosive rubidium hydroxide and hydrogen, a flammable gas. the heat of the reaction usually ignites the hydrogen. |
|
reactivity profile |
rubidium metal is a strong reducing agent. burns spontaneously in dry oxygen [mellor 2:468 1946-47]. readily catches fire in air when molten or with a sulfur vapor [mellor 2: 469 1946-47]. causes explosive decomposition of maleic anhydride. [chem safety data sheet sd-88 1962; chem. haz. info. series c-71 1960] burns in chlorine [mellor 2, supp. 1:380 1956]. interaction with mercury is exothermic and may be violent, [mellor, 1941, vol. 2, 469]. |
|
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. |
