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.

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.
