MSE PRO™ 4N (99.99%) Tungsten Oxide (WO3) Pieces (3-12mm) Evaporation Materials

Tungsten Oxide (WO3) is a chemical compound containing oxygen and the transition metal tungsten. It is frequently used in industry to manufacture tungstites for x-ray screen phosphors, for fireproofing fabrics and in gas sensors. Due to its rich yellow color, it is also used as a pigment in ceramics and paints. Tungsten Oxide thin films are desirable for use in many technologies, such as photocatalysts, gas sensors and electrochromic devices.
