Description:
Application of nano tungsten trioxide(WO3):
1. Gas-sensitive materials
Because of its small particle size and larger SSA, WO3 nanoparticle has significant surface effects, volume effects and quantum effects, and shows good gas-sensing properties.
2. Catalytic materials
WO3 is an important catalytically active material. WO3 has very good catalytic performance, can be used as both a main catalyst and an auxiliary catalyst, and it has a highly selective performance for many reactions.
3. Electrochromic materials
Nano WO3 film has broad application prospects in the fields of optical electrochromic smart windows, information displays, gas sensors, anti-reflection coatings of spacecraft, and infrared emission adjustment.
4. Other application fields:
WO3 nanoparticle used for solar energy absorbing materials and invisible materials
WO3 nanopowder used for producing hard alloy materials, high-temperature transparent material colorants, components of dielectric and piezoelectric ceramics, high-grade ceramic pigment components, etc.
Storage Condition:
