Nano particle size violet tungsten oxide for infrared thermal insulation nano material is a semiconductor material that has extremely wide applications in the fields of photoelectrochemistry. As you may have known, metal oxide semiconductor materials have a variety of excellent properties and play an important role in human life. Therefore, in recent years, how to reduce the production cost of semiconductor materials and increase the energy conversion rate has become a research hotspot. Among them, in the case of violet tungsten oxide powder, the preparation method should be first improved.
Scholars have discovered a method for producing hexagonal phase violet tungsten oxide. In this method, ammonium metatungstate (AMT) and glucose are mechanically mixed by grinding method, and calcined to obtain violet tungsten oxide powder. Such producing method is simple in process and high in efficiency. However, the mixing is uneven as it is produced by mechanical mixing. And the phase purity of the reaction product is insufficient. Meanwhile, the calcination temperature is high, and the particle size of the obtained product is large. Certainly, the preparation of violet tungsten oxide can also be achieved by other methods, but there are still some defects. Therefore, researchers are developing a new efficient and simple method for preparing nano particle size violet tungsten oxide.
