Using Activated Tungsten Oxide to Produce Tungsten Powder (2)

After many researches, the researchers found activated tungsten oxide is good for producing fine tungsten oxide than blue tungsten oxide. So compare the different between blue tungsten oxide and blue tungsten oxide.
The maximum content of the impurity element of activated tungsten oxide is similar with blue tungsten oxide. The mine phase of activated tungsten oxide phase is bronze (ATB) and the main phase of blue tungsten oxide is WO_2.9. The physical properties of activated tungsten oxide are: bulk density of it is 2.3 ~ 2.8g • cm^-1, -100 mesh sieve, specific surface area bigger than 3cm ² • cm^-3. Blue tungsten oxide physical properties is small different with activated tungsten oxide.

The study showed that in the same process, using activated tungsten oxide to produce tungsten powder there are little coarse crystalline grain and particle-piled which compare to blue tungsten oxide, besides tungsten powder are more uniformity and concentrated. So using activated tungsten oxide to produce tungsten powder is finer than using blue tungsten oxide.
