Nano tungsten oxide particles can be categorized based on their chemical composition and properties. Below are the main types:
- Yellow Nano Tungsten Oxide Particles (Yellow Tungsten Trioxide – YTO, WO3)
Definition:
Yellow tungsten oxide (YTO) is the most common type of nano tungsten oxide particle, with the chemical formula WO3. It is a pale yellow crystalline powder composed of hexavalent tungsten ions (W6+) and divalent oxygen ions (O2-).
Characteristics:
Yellow tungsten oxide particles are known for their stability, high tunability, and excellent optical and electronic properties. Their crystal structure is closely related to temperature and shows gas sensitivity, allowing them to detect gases like carbon dioxide and ammonia.
Applications:
These particles have broad applications in catalysis, sensors, and batteries. For example, they can act as a catalyst in chemical reactions or as a sensor component to detect harmful gases in the environment.
- Blue Nano Tungsten Oxide Particles (Blue Tungsten Trioxide – BTO, WO2.9)
Definition:
Blue tungsten oxide (BTO) is a mixed oxide of tungsten with the chemical formula WO2.9, appearing as a deep blue or blue-black crystalline powder.
Characteristics:
Blue tungsten oxide has a unique color and physical properties, with slightly lower oxygen content than yellow tungsten oxide, resulting in some differences in performance.
Applications:
Due to its distinct color and optical properties, blue tungsten oxide may be used in specialized applications that require particular optical or color characteristics.
- Violet Nano Tungsten Oxide Particles (Violet Tungsten Trioxide – VTO, WO2.72)
Definition:
Violet tungsten oxide, also known as purple tungsten oxide, is another type of mixed tungsten oxide with the formula WO2.72. Its purple hue is due to a further reduction in oxygen content.
Characteristics:
This purple color and unique physical properties provide certain advantages in specific applications.
Applications:
Applications for violet tungsten oxide may be customized based on its specific performance characteristics.
- Cesium Tungsten Bronze (Cesium Doped Tungsten Oxide – Cs0.33WO3)
Definition:
Cesium tungsten bronze (Cs0.33WO3), also known as cesium-doped tungsten oxide, is a modified form of tungsten oxide with cesium doping.
Characteristics:
Cesium-doped tungsten oxide possesses unique infrared absorption properties, making it valuable for infrared absorbers and thermal insulation materials.
Applications:
It can be used as an infrared absorber for stealth materials or as an insulating material to improve thermal efficiency in buildings.
Common Features of Nano Tungsten Oxide Particles
