Nano violet tungsten oxide for preparing nano-ceramic dispersion solution may be produced by a hydrogen reduction method. And as you may have known, yellow tungsten oxide (tungsten trioxide) and violet tungsten oxide can also be used to produce such thermal insulation dispersion solution.
Using the same batch of APT for hydrogen reduction, triclinic yellow tungsten oxide (WO3), hexagonal blue tungsten oxide (ATB) and monoclinic violet tungsten oxide (W18O49) can be obtained. That is to say, three different phases and different colors of tungsten oxides which can be separately produced by the same batch of APT are subsequently hydrogen-reduced under the same process conditions, wherein the tungsten powder prepared from violet tungsten oxide has the finest particle size and particle size. And the distribution is narrower.
If you want to produce the same grade of tungsten powder, you can use violet tungsten oxide instead of yellow tungsten oxide or blue tungsten oxide as raw material. And you can significantly increase the thickness of the layer, speed up the push boat, and allow the maximum reduction temperature to be appropriately reduced. Then, the productivity of tungsten powder can be significantly increased. And therefore, it saves energy and reduces costs. If you want to produce the required grade of tungsten powder, in addition to determining the appropriate hydrogen reduction process conditions, you should also select the appropriate tungsten oxide raw materials.
