Description of key information

Neodymium metal is insoluble in water.The solubility of Neodymium in a NDBFe alloy was determined as < 10 µg/l.
In a publication of Takaya et al. the water solubilty of Nd2O3 and a NdBFe alloy was determined. The solubility of Neodymium in water was very low:
72.3 and 0. 22 ppb after 1 day, 0.4 and 0.55 after 7 days for Nd2O3 and NdBFe alloy respectively.

Key value for chemical safety assessment

Water solubility:
10 µg/L
