Description

Tungsten Oxide (WO₃) Micron Powder, Purity: 99.99%, Size: 3 µm

Tungsten Oxide (WO₃) Micron Powder is a high-purity fine powder with particle size around 3 µm, characterized by its yellow to greenish appearance depending on oxygen deficiency and stoichiometry. As a transition metal oxide, WO₃ exhibits semiconducting, electrochromic, and photocatalytic properties, making it highly valuable across advanced material applications. It is chemically stable, has a high melting point of 1473 °C, and a density of 7.16 g/cm³, which contributes to its durability under harsh thermal and chemical conditions.

WO₃ is especially notable for its ability to undergo reversible electrochromic transitions, making it a critical material in smart windows, displays, and sensors. Its catalytic properties also make it useful in environmental applications, including gas sensing and photocatalytic degradation of pollutants.
