Reduction of NbCl5 with H2
at 2 atm. (generated when the
tube is filled at STP, sealed and then heated). The reaction does
not go to completion and NbCl5 and NbCl4 must be separated by
sublimation. | [Purification Methods]
NIOBIUMCHLORIDE is Purified by filter and wash with THF and dry under vacuum.
