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.

http://www.element-collection.com/html/samples.html is located in London (im 99% sure)

 

he works with theo gray from the periodictable.com site

 

where are you exactly?

 

are you ordering as an individual or a company? lots of chem suppliers wont sell to individuals

Im an individual. I found somewhere, but thanks for the link- very reasonable prices there, cheers.

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.
