Description of key information

Calcium molybdate is not auto-flammable.

Key value for chemical safety assessment

Additional information

Self-ignition is not considered to be of relevance for this substance, since this would require heat to be developed either by reaction of this substance with oxygen or by exothermic decomposition and which is not lost rapidly enough to the surroundings. Calcium molybdate contains molybdenum in its highest oxidation state (+VI) included in stable, crystalline matrix. It is intrinsically not combustible and can safely be assumed not to be ignitable or auto-flammable. The high melting point of 1520 °C supports this assessment. In conclusion, the conduct of further experimental verification is not considered to be required (in accordance with section 1 of REACH Annex XI).
