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. Taking shotguns as an example, the melee weapon of Chinese special forces is QBS09 military shotguns, which are different from the traditional shotguns equipped with gunpowder, steel or lead-iron balls, such as American No.00 deer bombs, etc. QBS09 military shotguns using tungsten alloy and…

Tungsten Trioxide is a semiconductor material with great development potential. In recent years, scientific research achievements have been made in the fields of new energy batteries, electrochromic devices, photocatalysts and supercapacitors. Industry flexibly chooses preparation methods according to different needs, among which precipitation method is a popular preparation method of Tungsten Trioxide. 1.Principles Precipitation method refers to adding a solvent which is miscible with the solution into the solution of mixed components, and changing the solubility of some components in…

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…

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. 1.The origin of hydrothermal synthesis method When it comes to hydrothermal synthesis, we have to mention hydrothermal method, which was studied by geologists in the mid-19th century by simulating…

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. It is known that in the past, radiation protection mainly included lead-boron polyethylene, boron-containing polypropylene, cadmium plate, boron steel, tungsten-based high molecular weight alloy, boron carbide and aluminum-based boron carbide. Only Pb-B polyethylene can shield X-rayY-Y-ray neutron at the same time, and other materials may only shield one…

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. Firstly,…

Tungsten Trioxide, also known as tungsten oxide (WO 3), has been widely used in many fields such as petrochemical industry, photoelectric information, national defense and military industry because of its special properties such as catalysis, optics and electricity. Tungsten Trioxide is mainly used as a catalyst in the petrochemical field. When it is used as a catalyst, it not only has high catalytic activity, long service life, but also is environmentally friendly, non-toxic and pollution-free. Basically, there is no need…

Ⅰ What is Tungsten Alloy? There are two definitions of tungsten alloy: (1) tungsten alloy in a broad sense: metal materials containing tungsten are collectively called tungsten alloy, such as tungsten-iron alloy, tungsten-copper alloy, tungsten-nickel alloy and cemented carbide; (2) Tungsten alloy in a narrow sense: an alloy material composed of tungsten as a matrix material and a small amount of metal binders such as nickel, copper, iron, cobalt, molybdenum and chromium, also known as high specific gravity tungsten alloy…
