CAS number: -
Ytterbium stabilized Zirconium and
Hafnium Oxide is a non-combustible, white powdery inorganic solid. The
substance shows no self-ignition at a temperature of 400 °C and the
melting point is approximately 2.700 °C. The relative density is 6.14 g/cm³
at 20 °C. The substance is considered highly insoluble in water.
The transformation / dissolution (T/D) test with Ytterbium stabilized
Zirconium and Hafnium Oxide at pH 8 reveals that only ytterbium is
released to the aqueous environment. An average metal release of 0.07
µg/L was measured after 7 days T/D protocol at pH 8. The mean diameter
of the Ytterbium stabilized Zirconium and Hafnium Oxide particles (D50
value) is 72.56 µm.
