Description of key information

Zirconium zircon with encapsulated cadmium selenium sulphide (CAS 102184 -95 -2) is an inorganic, odourless powder with a bright red colour.

- Melting point > 1000 °C

- relative density: 4.74.

- Particle size distribution: d10 = 4.4 µm, d50 = 11.4 µm, d90 = 23.3 µm

- Dustiness:

total: 61.99 mg/g

MMAD= 23.59 µm, GSD= 2.75

Fractional deposition in human respiratory tract: Head (ET): 51.8 %, Tracheobronchial (TB): 0.5 %, Pulmonary (PU): 0.7 %

- The transformation/dissolution

As dissolved Cd, Se and Zr concentrations were below 3.6 µg/L even at the highest loading of 100 mg/L, referring to a solubility of < 0.004 %. Thus, the extent to which "Zirconium zircon with encapsulated cadmium selenium sulphide" can produce soluble available ionic and other metal-bearing species in aqueous media is limited.
