Dark blue nano tungsten oxide may be applied for producing thermal insulating glass. I believe that almost everyone knows the existence of heat insulating glass, but the answer of “What is dark blue nano tungsten oxide powder?” is not necessarily clear. In fact, this nano grade blue tungsten oxide can be used on glass to shield most of the ultraviolet rays. Therefore, researchers are focused on studying this material. And therefore, the raw material for producing blue tungsten oxide, ammonium paratungstate, is also one of the research targets of researchers.
Some researchers have observed the crystal morphology of regular-shaped ammonium paratungstate and common-shaped ammonium paratungstate, and found that:
1.0 Regular type ammonium paratungstate has a uniform grain size and a smooth surface with sharp edges. Besides, there is almost no agglomeration.
2.0 Common type ammonium paratungstate has uneven grain size and incomplete surface growth, just like wind-eroded rock. There is also certain agglomeration.
