Description of key information

Adsorption/desorption screening is not required, based on the physical and chemical properties of the substance.

Key value for chemical safety assessment

Additional information

A partition coefficient is not available for Silicon Nitride as it is an inorganic substance with low water solubility. It would be expected to have a low potential for adsorption, being an inorganic substance with no lipophilic nature.
