Hazard Predictions

• Potentially hazardous: May be hazardous but unknown

The combination of metal hydrides or alkyls with metal nitrides may result in a hazardous reaction, depending on the specific materials involved. Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility.

Lithium hydride, calcium hydride, and titanium hydride react with molecular nitrogen in the high temperature, high pressure synthesis of metal nitrides, so these hydrides are unlikely to react with metal nitrides even under extreme conditions (Rittmeyer, P., U. Wietelmann. 2002. Hydrides. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online)).

Silicon nitride is stable to reduction up to 1750 C, and aluminum nitride is produced in a reducing environment at 1690 C, so these compounds are likely to be stable when in contact with metal hydrides, which are reducing agents (Roberts, K. L. and Covington, L. 2005. Nitrides. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).
