Application

Tungsten(VI) oxide serves multiple purposes across various industries, owing to its unique chemical and physical properties. This transition metal compound, commonly appearing as a canary-yellow powder that darkens to orange upon heating, is insoluble in water but can dissolve in caustic alkalies and acids with some difficulty. Its noncombustible nature makes it valuable in creating tungstates for use in x-ray screens and for fireproofing fabrics. Additionally, tungsten(VI) oxide is employed in manufacturing x-ray screen phosphors, gas sensors, and in pigmentation for ceramics and paints. Its role extends to the development of electrochromic or smart windows, and it holds promise as an efficient photo-catalyst under visible light when paired with titanium dioxide. Recent advancements highlight its potential as an anode material for high-performance lithium-ion batteries, showcasing its versatility and importance in technological applications.
