Used as a precursor in the production of tungsten metal and tungsten-based materials, especially in semiconductor manufacturing and microelectronics. Serves as a component in certain high-temperature oxidation-resistant coatings due to its thermal stability, and is utilized in the ceramics industry to enhance strength and high-temperature resistance. Investigated for use in gas sensing applications because of its electrical properties that change in response to environmental gases. Also explored in photocatalytic systems for water treatment and energy conversion under visible light illumination, and shows potential in batteries and energy storage devices due to its good electrical conductivity and chemical stability.
