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 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.

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 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.

Tungsten Trioxide, also known as tungsten anhydride (WO 3), is a yellow powder, insoluble in water and alkali, and slightly soluble in acid. It is widely used in our daily life and industry, but it itself is harmful. Therefore, when using Tungsten Trioxide, attention should be paid to the safety issues related to Tungsten Trioxide. The safety issues of WO 3 include avoiding human contact during use, keeping away from flammable materials during storage and emergency treatment after use.

Tungsten Alloy is an alloy produced by powder metallurgy with tungsten powder as main raw material and Fe, Ni, Co as binder. It has excellent uses such as high melting point, high hardness, high strength, high specific gravity, creep resistance, thermal conductivity and electrical conductivity, and is widely used.

Tungsten Alloy is an alloy with tungsten as the main element and added with Ni、Cu、Co、Mo、Cr and other elements. It has a series of excellent characteristics: the density is as high as 16.5-19.0 g/cm3; The specific gravity is 16.5-18.75 g/cm3. The tensile strength is 700-1000 MPa. Strong ability to absorb rays, 30-40% higher than lead; The thermal conductivity is 5 times that of die steel. The coefficient of thermal expansion is small, only 1/3-1/2 of iron or steel; Good weld ability and mach inability.

The climax of research on the brief history of tungsten alloy development is mainly pided into the following four stages:
