Yttrium Trichloride (YC13)?
« on: January 08, 2008, 07:07:55 PM »
Hello, I recently was searching a Element collecting site, and came upon a listing for a compound of Yttrium Trichloride, ampouled under Argon gas.

Could someone explain what is the attraction of this compound to element collectors and what makes this a rare chemical, as it seems to be selling very fast?

Excuse my iqnorance, but would appreciate any insight.

Many thanks

Yttrium in elemental form is highly reactive and dangerous.  The common oxidation state is +3 and is therefore kept as a trichloride because of stability.

Thank you for your reply concerning the yttrium trichloride, so if one purchases pure elemental
yttrium metal sealed in argon in a ampoule as most dealers offer it, will remain safe and unaffected as long as kept sealed?
thanks again

Thinking about it again, Yttrium is somewhat stable in air and should be suitable in a ampule sealed with Argon.  I believe the reason that it is sold as YCl3 is due to availability and difficulty of obtaining purity of elemental Yttrium. (Which probably means it is expensive)
