Description of key information
Additional information
Niobium carbide (NbC) is a solid inorganic substance which forms grey cubic crystals. The melting point of niobium carbide (NbC) is 3608 °C, the boiling point is 4300 °C. The density of niobium carbide (NbC) at room temperature is 7.82 g/cm³. The mean diameters determined by volumetric distribution are as follows: D (v, 0.1) = 1.10 μm; D (v, 0.5) = 2.12 μm; D (v, 0.9) = 4.11 μm
The highest measurable water solubility in T/D test was 6.47 µg/L (10 mg/L loading, 7 days, 21.5 °C.
The self-ignition temperature of niobium carbide is 297 °C.
The substance is considered non-flammable and non-explosive and does not have oxidising properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
