Fine Tungsten Powder Obtained with Blue Tungsten Oxide through the Hydrogen Reduction
Fine tungsten powder is prepared with blue tungsten oxide (BTO) through the hydrogen reduction.The samples were characterized with the scanning electron microscope (SEM), fisher sub-sieve sizer (FSSS) and the particulate size description analyzer (PSDA).Fine tungsten powder is easily obtained when the reduction temperature is low.With the increasement of the reduction temperature, the grain size of tungsten powder becomes coarse.The increase of the weight of BTO in the ceramic boat leads to the increasement of the thickness of its bed.Therefore, the weight of BTO in the ceramic boat ought to reduce if fine tungsten powder is prepared.Fine tungsten powder can be obtained when the hydrogen flow increases.
