Description of key information

Additional information

This UVCB is a black/brown, odourless solid (at 20°C and 101.3 kPA) in the form of granules (coarse chunks). The density will vary according to the precise composition of the sample. The density of the tested samples was and 3.54 and 4.71 g/cm3. The melting point is shown to be > 500°C. Consequently, boiling point and vapour pressure cannot be determined. The water solubility test shows dissolution of metal ions although the test results should be used with caution.

There is no evidence of physical hazards in terms of (auto)flammability, explosivity and oxidizing properties.

Studies regarding flash point, partition coefficient, surface tension and particle size distribution do not need to be conducted. Waivers are in place for all these endpoints.
