EC number: 215-231-4
CAS number: 1314-35-8
Justification: According to the ECHA Guidance on
information requirements and chemical safety assessment Chapter R.7a.:
Endpoint specific guidance May 2008, when an inorganic element is in its
highest possible oxidation state is incapable of further reaction with
oxygen and can thus be designated as non-flammable. The highest
oxidation state of tungsten is VI and the oxidation state of tungsten in
this compound is VI. Thus, the substance can be considered non-flammable
in tungsten trioxide
highest possible oxidation state and
incapable of further reaction with oxygen.
Thus, tungsten trioxide
can be considered non-flammable and non-pyrophoric.
