About:
Grade: WO3-0
Appearance: Yellow/Bright Green Crystallized Powder

Tungsten trioxide is almost exclusively manufactured by the calcification of APT under oxidizing conditions (in air).  WO3 is one of the most important, highly pure intermediates for the production of other tungsten compounds including tungsten metal powder. Because of its bright yellow color it is used as a pigment in oil and water colors. It is employed in a wide variety of catalysts, most recently for the control of air pollution and industrial hygiene (DeNOx).
