NIOBIUMCHLORIDE Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
Brown-black crystal needles; pure brown in transmitted light.
Decomposes on exposure to air and moisture (color change first to black,
then to white). Dissolves in a small amount of H2O and in dilute
hydrochloric acid, giving a dark-blue solution.
synthetische
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.
