TUNGSTEN (IV) OXIDE Usage And Synthesis
Chemical Properties
brown powder(s), may become purple on standing; formed when WO3 is reduced by H2 at 575°C–600°C [KIR83] [STR93]
Uses
Tungsten(IV) oxide is used in the production of tungsten and tungstates, in alloys, in fire-proofing fabrics and as a ceramic pigment. It is used to study their chromism, photocatalysis and sensing capabilities. It is associated with rhenium trioxide particles and used for detection of protonatable, radical and precharged species under laser desorption ionization.
Flammability and Explosibility
Non flammable
