Tungsten Oxide (WO3) Evaporation Material Specifications

Properties	Details
Chemical Formula	WO₃
Appearance	Yellow crystalline solid
Molecular Weight	231.84 g/mol
Density	About 7.16 g/cm³
Melting Point	1473℃
Boiling Point	1700 - 1800℃ (sublimation may occur)
Crystal Structure	Orthorhombic; space group Pnma, with tungsten atoms octahedrally coordinated by oxygen atoms
Solubility	Insoluble in water and most common organic solvents. Soluble in aqueous alkali solutions (e.g., NaOH) to form tungstate salts (e.g., Na₂WO₄)
Acid - Base Properties	Amphoteric; can react with both acids and bases. With strong acids, it can form complexes; with bases, forms tungstate anions
Redox Properties	Can act as an oxidizing agent. Can be reduced to tungsten metal (W) or lower oxides (e.g., WO₂) by reducing agents such as hydrogen (H₂), carbon (C), or carbon monoxide (CO)
Electrical Properties	Semiconductor; conductivity can be modified by doping or changing the microstructure
Optical Properties	Exhibits photochromic and electrochromic properties; absorbs ultraviolet and visible light to some extent; high refractive index
Thermal Properties	Good thermal stability; thermal expansion coefficient is relatively small

Tungsten Oxide (WO3) Evaporation Material Applications

Electrochromic and photochromic: WO₃ has the characteristics of electrochromic and photochromic. In electrochromic devices, when voltage is applied, the color of WO₃ changes, which can be used in smart windows, electronic displays, etc. In terms of photochromism, it can be used in optical recording materials and optical sensors, etc.
Catalyst: It is an important catalyst that can be used in many chemical reactions, such as oxidation reactions, hydrogenation reactions, etc.
Gas sensor: Because its adsorption and reaction to certain gases (such as hydrogen, ammonia, etc.) will cause changes in electrical properties, it can be used to prepare gas sensors for detecting harmful gases or important industrial gases in the environment.
