At room temperature, the substance is a solid.
The majority of the available data on physical and chemical properties of the UVCB is taken from the report Liipo, et al, 2010 and Liipo et al. 2014 –a comprehensive study performed on the UVCB to characterize it (physico-chemical and mineralogical properties) in view of the upcoming REACH registrations of copper intermediates by the REACH Copper Consortium.
In particular, a comprehensive chemical and mineralogical characterization of a representative sample was performed (and reported under IUCLID 4.23). The study from Liippo et al (Outotec Lab) furthermore includes thermo gravimetric /differential scanning calorimetric (TG/DSC) measurements (under Air flux and Nitrogen atmosphere) that allowed determining melting, oxidation and related thermal stability properties of the UVCB.
The Outotec study included: Chemical assays (Inductively coupled argon plasma optic emission spectrometer, sulphur and carbon analyzes, Measurement of amount of magnetic material), Granulometry, density and specific surface measurements, determination of melting and oxidation temperatures (Thermogravimetry / differential scanning calorimetry), Water solubility tests, Mineralogical characterization (X-ray Diffraction, Optical Microscopy, Scanning Electron Microscopy) and Mineral Quantification. Based on the tests results, the study furthermore includes expert judgements addressing flammable, self-ignition, explosive and oxidising properties of the materials.
The selection and collection of the representative samples was made based on expert knowledge and according to standardized sampling protocols developed by the REACH Copper Consortium, an industry joint-venture regrouping major manufacturing and importing companies of the UVCB substance. Details on the sampling approach and the representative samples are reported as supporting information in IUCLID 1.4 and 4.1.
The relevant physico-chemical properties of the materials (as well as IUCLID sections) are summarised below:
