Description of key information

Additional information

The defining characteristic of the inorganic diniobium pentaoxide is its insolubility in water. Diniobium pentaoxide remains stable in water and does not hydrolyse. It cannot be adsorbed and metabolised by living beings but would be excreted and thus does not bioaccumulate.Based on its intended uses (manufacture of superalloys, as a catalyst or to produce lenses) the substance is not expected to enter into the environment by any pathway. The oxide is not volatile and does not enter into the atmosphere. Biodegradation cannot be assessed since diniobium pentaoxide is inorganic. The substance is judged to be an inert, harmless substance which according to its uses does not enter the environment. Consequently, environmental effects have never been reported.
