Tungsten Trioxide is an oxide of tungsten and an important industrial raw material, which is widely used in many fields because of its good properties. For example, in the military field, it is often used as an important invisible material because of its strong ability to absorb electromagnetic waves. At present, there are several methods to prepare Tungsten Trioxide, among which sol-gel method, which has the advantages of simple process, less environmental pollution, less corrosion to equipment and relatively low production cost, is more popular.

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.

Tungsten Alloy is often used in harsh environments because of its high density, strength, good plasticity and hardness, such as bullets in military fields, prefabricated fragments of tungsten alloy, kinetic energy armor-piercing projectiles and so on.

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.
