Tungsten oxide (Tungsten Oxide, WO3) can present different appearance colors under different crystal structures and forms. The following are the common appearance colors of tungsten oxide:
Tungsten Trioxide (WO3)
The color of tungsten trioxide can vary depending on the crystal structure and particle size. Normally, pure tungsten trioxide is yellow to light yellow. However, as particle size varies, color variations may occur, including light blue, light green, or milky white.
Tungsten Dioxide (WO2)
Tungsten dioxide is usually dark brown. Its apparent color comes from its ability to absorb and reflect light.
Tungsten Suboxide
The appearance color of tungsten suboxide is usually between black and blue-black. The exact color may vary depending on the preparation method and reaction conditions.
In addition, tungsten oxide is also available in blue, purple and pink colors. The color of tungsten oxide can be affected by many factors, including crystal structure, particle size, surface modification, presence of impurities, etc. In addition, differences in purity and form may also cause color variations. Therefore, the color of tungsten oxide may vary in specific applications or products.
