Used as a precursor in the production of tungsten metal, which is essential for manufacturing high-strength alloys and filaments in light bulbs. Commonly employed in gas sensors due to its sensitivity to reducing gases like hydrogen and carbon monoxide. Utilized in electrochromic windows that change color or transparency when voltage is applied, helping control light and heat in buildings. Acts as a photocatalyst for breaking down organic pollutants under light exposure. Frequently added to ceramic glazes and pigments to produce yellow to orange colors. Also found in some types of welding electrodes and radiation shielding materials. Additionally, it is being researched for use in lithium-ion batteries and energy storage materials due to its structure that supports ion intercalation.
