Is Tungsten Oxide Flammable?

Tungsten oxide (WO3) itself is non-flammable at room temperature. It is an inorganic compound and will not spontaneously ignite or support the combustion process. Therefore, tungsten oxide alone is generally considered a non-combustible substance.

However, it should be noted that when tungsten oxide exists in powder form, it may be explosive under certain conditions due to its high specific surface area and the fineness of the particles. Factors such as the particle size and concentration of the powder, the build-up of electrostatic charge, and the exposure of tungsten oxide to other combustible substances all affect its explosiveness.

When handling and storing tungsten oxide powder, proper precautions need to be taken, such as avoiding ignition sources, electrostatic discharge and dust emission, to reduce the potential risk of explosion. At the same time, follow the safe operating procedures and relevant regulations to ensure that the environment for storing and using tungsten oxide is safe.

In conclusion, tungsten oxide itself is not flammable at normal temperature, but tungsten oxide powder may be explosive under certain conditions. Therefore, proper safety measures should be taken when handling and storing tungsten oxide powder.
