Tungsten oxide is used for the production of tungsten metal powder or as compound and pigment for ceramics. Two commercial grades are available:
1. Tungsten Blue Oxide WO2.97 has a deep blue colour.
2. Tungsten Yellow Oxide WO3 has a yellow to bright green colour.
 
Yellow tungsten oxide (WO3 - YELLOW OXIDE) is a finely divided, yellow crystalline powder. It is produced by roasting ammonium paratungstate at closely controlled temperatures to drive off combined water and or water and ammonia. Exact time and temperature control determines, to a large extent, the physical characteristics of the tungsten oxide.
