Description of key information

Cerium tetranitrate is concluded not to be flammable based on its inorganic nature. Furthermore, from day to day handling of the substance, cerium tetranitrate is concluded not to have pyrophoric properties nor to be flammable in contact with water.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Cerium tetranitrate being an inorganic substance, will not have a potential for flammability. Furthermore, cerium in cerium tetranitrate is in its highest possible oxidation state and is thus incapable of further reaction with oxygen. Reference can also be made to cerium trinitrate which was tested in an A.10 test and revealed a negative result. The presence of nitric acid does not influence the conclusion as this substance was officially classified in physico-chemistry, but not for flammability.

Justification for classification or non-classification

Pyrophoricity.

In the daily use and handling of cerium tetranitrate during which continuous exposure to air can occur, no spontaneous ignition is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that cerium tetranitrate has pyrophoric properties.

Flammability in contact with water.

Cerium tetranitrate is produced in an aqueous solution. In contact with water no ignition and/or liberation of flammable gases is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that cerium tetranitrate is flammable in contact with water.

Flammability.

Based on its inorganic nature, cerium tetranitrate is concluded to be not highly flammable. Furthermore, cerium in cerium tetranitrate is in its highest possible oxidation state and is thus incapable of further reaction with oxygen and can therefore be designated as non-flammable. This results in an absence of classification under both DSD and CLP systems.
