Abstract
It is found that very finely divided silicon nitride made by plasmochemical synthesis has more pronounced general toxicity and cytotoxicity than coarse material made by nitriding silicon. It is proposed to reduce the maximum permissible concentration for ultrafine silicon nitride powder from 6 mg/m3 to 1 mg/m3.
