The MECS ® Cesium Catalyst range is formulated to enable low plant stack emissions and lower ignition temperatures for faster sulfuric acid plant start-up. Instead of the standard vanadium catalyst formulation with potassium promoter, this catalyst contains the more active cesium as promoter to activate the catalyst at lower temperatures.

Cesium-137 is also commonly used in hospitals for diagnosis and treatment, as a calibration source, and large sources can be used to sterilize medical equipment. How does cesium change in the environment? Cesium-137 decays in the environment by emitting beta particles. As noted above, cesium-137 decays to a short lived decay product, barium-137m.

Caesium gets its name from the Greek for heavenly blue. Not for its eyes (it's only an element!) but less romantically for the appearance of its emission spectrum in the spectroscope. Caesium was discovered in 1860 by Robert Bunsen (he of the burner fame) and physicist Gustav Kirchhoff.

Caesium: isolation. Isolation: caesium (cesium in USA) would not normally be made in the laboratory as it is available commercially. All syntheses require an electrolytic step as it is so difficult to add an electron to the poorly electronegative caesium ion Cs +. Caesium is not made by the same method as sodium as might have been expected.
