EC number: 945-888-9
CAS number: -
Zirconium oxide, hafnium and ytterbium doped 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 Zirconium oxide,
hafnium and ytterbium doped 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 Zirconium oxide, hafnium and ytterbium doped particles
(D50 value) is 72.56 µm.
