Where to obtain Caesium

[Sylar]

Please can someone tell me where I can obtain some Caesium in Europe that is not from here http://www.elementsales.com/

I had a good place bookmarked but then lost it.

 

Any help would be greatly appreciated. Thanks in advance.

Well, if you want to make it yourself, get the caesium mineral pollucite and powder it, then putting it in a solution of sulfuric acid to get acesium alum (CsAl(SO₄). Roast this with carbon, then add water toget cesium sulfate (CsSO₄). Now that the sulfate is in aqueoussolution, add barium azide (Ba(N₃)₂ to get cesium azide(CsN₃). Heat this to 800 degrees C to get exceptionally pure cesium.

Please! No one try to prepare barium azide outside of a professional or academic laboratory! You will lose a finger. Preparing cesium metal is also dangerous. Cesium comes in vacuum sealed ampules for a reason. Barium azide if both explosive and toxic. The preparation of cesium metal is best left to Sigma-Aldrich.
