Technical profile of Tungsten Trioxide, a high-purity raw chemical material supplied by Triveni Chemicals for industrial manufacturing and laboratory synthesis.


Tungsten Trioxide is an inorganic compound widely used for its electrochromic, catalytic, and semiconducting properties. It appears as a yellow to greenish crystalline powder, insoluble in water, and stable under normal conditions with high thermal stability. It exhibits strong light absorption and can change color under applied voltage, making it useful in electrochromic applications.
It is extensively used in smart windows, displays, and electrochromic devices where reversible color change is required. In catalysis, it is used in oxidation reactions and petroleum refining processes. It also serves as a key material in gas sensors, especially for detecting nitrogen oxides and other gases. In addition, it is used in pigments, ceramics, and solar energy devices. Its semiconducting nature makes it valuable in photocatalysis and environmental applications such as air purification.
