Blue Tungsten Oxide Preparation out of Ammonium Paratungstate Self-Reduction

Hydrogen produced in the cracking process of heated Ammonium paratungstate is used for the self-reduction of the cracked products. The impacts on blue tungsten oxide's properties by the major reduction parameters, including temperature and rotary kiln speed without ammonia or hydrogen. The application of this technology to environmental protection, energy conservation and production safety are focused.
