Title: inorganic question ( Nb to Nb(V) )
Post by: L42L on July 12, 2004, 04:49:00 PM

Inspired by demorols post (# 518590); how would one go from Niobium metal to Niobium (V) Chloride? (NbCl5)

I believe it is the highest oxidation state of Niobium.

Tube furnace/Cl2 gas? How hot?

Electro chem?

Some Aqua Reagia round about way?

Any thoughts are appreciated.

Thanks!

Title: Nb(V) salts hydrolize

Surelly not with aqueous chemistry, so you can forget aqua regia, electrolysis and similar. Nb(V) salts hydolize to Nb2O5.
I suspect you would need a high temperature chlorination with Cl2. So like you already suspected you would need a special furnace for that.

this is what i have on my computer, and it is understandable.
