1. WO3 is used as gas sensor and photocatalytic paint;
2. WO3 nano powder also used in Solar photosensitive film;
3. For the X-ray shielding fabric is also available to use the Nano Tungsten trioxide powder;
4. The modified material doped tungsten doping like Cs modified Tungsten oxide powder;
5. Usually WO3 is applied as petrochemical catalytic or co-catalyst. For the catalytic properties is the use more often of WO3 in dehydrogenation hydrogenation, oxidation, isomerization of hydrocarbons, alkylation reactions and also commonly used in oil and chemical catalysts.
