Violet tungsten oxide (referred to as “violet tungsten”) is an inorganic compound composed of tungsten and oxygen. It is an oxygen-deficient oxide with a molecular formula of WO2.72 or W18O49. All are needle-shaped or rod-shaped, and each particle has abundant cracks inside, which makes violet tungsten have excellent physical and chemical properties and is widely used in many fields.
The main uses of purple tungsten oxide are as follows:
- Making tungsten products
Ultrafine tungsten powder: It is produced by hydrogen reduction of violet tungsten, and its characteristics include fast speed, many crystal nuclei and fine particle size.
Tungsten carbide: First, tungsten powder is prepared from purple tungsten oxide, and then tungsten carbide can be produced from the tungsten powder through the carbonization process.
- As lithium battery anode material
Violet tungsten is suitable for making lithium battery anode materials because of its high theoretical specific capacity, fast ion transport rate and large porosity. It can not only prolong the mileage of the battery, but also improve the charge and discharge performance.
- Making dimming glass
Violet tungsten has become an important raw material for the preparation of dimming glass because of its good electrochromic and photochromic effects, as well as its strong absorption of electromagnetic waves, and can endow the glass with a color-changing function.
- Making near-infrared photothermal diagnosis and treatment drugs
Violet tungsten has excellent optical properties and has a strong absorption ability in the near-infrared region, so it can be used to prepare near-infrared photothermal diagnosis and treatment drugs, which has great application value in cancer treatment.
- Making photocatalyst
Violet tungsten has a high solar energy utilization rate and good photocatalytic performance due to the rich cracks inside the particles and the high concentration of oxygen defect structure, and is suitable for use as a photocatalyst to reduce water pollution.
- As a shielding material
As a shielding material, violet tungsten has the advantages of good insulation effect, good air permeability, and easy washing. It can be made into metal fiber radiation protection clothing and used in new solar heat shield fusion devices.
- As a fuel cell carrier
Violet tungsten can partially replace carbon as a fuel cell carrier, which can effectively improve the corrosion resistance of the catalyst and prolong the product life.
- The production of gas sensors
Due to its novel acoustic properties and high sensitivity, violet tungsten can be used to make gas sensors, such as nitrogen dioxide gas sensors and hydrogen sulfide gas sensors.
