- Ammonium Paratungstate
is the main intermediate produced at Micrometals Technology. APT is calcined to yellow or blue oxide 
.
- Yellow or blue oxide is then reduced to tungsten metal powder by dry hydrogen. The reduction is carried out in pusher furnaces, in which the powder passes through the furnace in boats at 700-1000°C depending on the desired particle size.
