Tungsten Trioxide (WO3) is an important N-type semiconductor material, which has excellent photoelectric properties and has a wide application prospect in solar cells, photoelectric devices, photocatalysis, sensor materials and other fields. At present, there are many commonly used methods to prepare Tungsten Trioxide, among which hydrothermal synthesis is a common one.

With the development of society, Tungsten Trioxide has been widely used in many fields such as batteries, ceramic raw materials, target, dimming glass and so on because of its special properties such as electrochromic, photochromic and gas discoloration. Because of the different application fields of WO 3, its preparation method can be chosen flexibly according to needs. There are several well-known methods to prepare WO 3: hydrothermal synthesis, sol-gel method, precipitation method, template method, gas-liquid reaction method and microemulsion method.

Tungsten Trioxide is widely used in many fields due to its catalytic, optical and electrical properties.According to different application fields, the selection of preparation methods is different.Commonly used preparation methods of Tungsten Trioxide include hydrothermal synthesis method, sol-gel method, precipitation method, template method, gas-liquid reaction method and microemulsion method.In actual production practice, we should choose the appropriate preparation methods flexibly according to the advantages and disadvantages of each method.

Tungsten trioxide is a yellow powder, which can be made into metal fiber radiation protection clothing for medical protection. It is characterized by strong shielding effect, good air permeability and good washability.
