Description of key information
The self-ignition temperature of the test substance niobium carbide (NbC) was measured with 297 ºC.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 297 °C
Additional information
The objective of the study (in accordance to EU method A.16) was to provide information on the auto flammability of the inorganic test substance niobium carbide. A certain volume of NbC (niobium carbide) was placed in an oven at room temperature; the temperature/time curve relating to conditions in the centre of the sample was recorded while the temperature of the oven was increased to 400 ºC, at a rate of 0.5 ºC/min. The test substance NbC (niobium carbide) revealed a self-ignition temperature of 297 ºC.
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.
