Description of key information

Silicon Nitride does not posess oxidising properties on the basis of a theoretical assessment.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as the substance, Silicon nitride, does not contain oxygen or halogen atoms chemically bonded to nitrogen or oxygen.

Justification for classification or non-classification

Silicon nitride was found not to posess oxidising properties on the basis of a theoretical assessment; on this basis it is considered that silicon nitride should not be classified as an oxidising solid within the meaning of the CLP Regulation.
