Preparation of defective tungsten oxide nanopowder is widely studied as defective tungsten oxide nano powder has wide applications in solar power generation, seawater desalination, and sewage treatment. Defective tungsten oxide nanopowder is a kind of photothermal conversion material, which can convert sunlight into heat energy to heat the base liquid, and realize the photothermal conversion. Specifically, the application of tungsten oxide nanoparticles is to convert water into steam on a large scale under the radiation of the sun or solar…

WO3 nanopowder is n-type semiconductor that has wide applications in smart windows, gas sensors, etc., so it has been paid much attention including its preparation. Here is a preparation method of WO3 nanopowder. More details, please visit: http://tungsten-oxide.com/index.html Preparation of WO3 Nanopowder Weigh and dissolve a certain amount of Na2WO4·2H2O (analytical purity) in deionized water to prepare a sodium tungstate solution. The solution was heated to 70-80 °C, and 1 mL of PEG-400 was added to the solution. Add three…

WO3 nanopowder is a typical n-type gas-sensing material that has high sensitivity and selectivity to toxic gases, so it has a wide application in gas sensor to detect various hazardous gases. Especially for trimethylamine gas, the reaction is rapid, and the sensitivity is very high. It means that the WO3-based gas sensor provides a quick, convenient, and accurate detection method for detecting whether fish or shellfish food has deteriorated. Also, the gas sensor based on WO3 nano particles has the…

As a gas sensing material, WO3 on the nanoscale has good gas sensitivity and selectivity towards H2, CO, H2S, NH3, NOx, O3 as well as some organic gases. WO3 nano powder is a typical n-type semiconductor that is considered to be the promising material to fabricate the gas sensor, which has a widespread utilization in the environment detecting and the safety monitoring. When WO3 nanopowder contacts the gas to be measured, its resistance changes, so that the output signal changes…

Warhead is a very important part of the projectile weapon that can kill enemies and destroy the enemy’s weapons, equipment, and facilities. Tungsten heavy alloy has unique performance, such as high density, high melting point, high strength, and good machinability, so it is widely used to fabricate warheads. More details, please visit: http://www.tungsten-alloy.com/en/alloy04.htm Types of tungsten heavy alloy warheads include: Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. Explosive: An explosive charge is used to…

Tactical missile is designed for short-range battlefield use and has become one of the important weapons in modern warfare. Its warhead is mostly composed of tungsten alloy fragments with greater lethality, for targets within 1000 kilometers. Tactical missiles are mainly used to attack nuclear attack weapons, assembled troops, tanks, aircraft, ships, radars, command posts, airports, ports, railway hubs, and bridges within the tactical depth of enemy campaigns.

How to make shaped charge obtain a more ideal armor piercing effect? It is a good idea to choose tungsten alloy as the material of shaped charge liner material. The armor piercing ability of shaped charge is proportional to the square of the density of shaped charge liner material. Therefore, the use of high density tungsten alloy shaped charge liner can make the shaped charge achieve better armor-piercing effect. More details, please visit: http://www.tungsten-alloy.com/en/alloy04.htm According to the experts, tungsten alloy…

Tungsten alloy applied for military defense is tungsten heavy alloy that is 90% to 97% pure tungsten in a matrix of nickel and copper, or nickel and iron. Why these alloying elements are necessary? That is because pure tungsten is very difficult to machine or fabricate, addition of these elements improves both the ductility and machinability of the alloys while retaining its high density. These tungsten heavy alloys are ideal for high density applications where machining is required. For example,…

Tungsten alloy applied for gyroscope of antiship missile is an alloy composed of tungsten (W) as a matrix and Ni, Fe, Cu, Co, Mn and other alloying elements to form a composite structure of tungsten particles and bonding phase. The navigation gyroscope is the heart of navigation and control systems of antiship missiles and even submarines, torpedoes, satellites, rockets, and aircraft. At present, there are various advanced navigation technologies in the world, but the inertial guidance gyroscope is still the…

It has been reported that tungsten alloy is widely used in the weapon industry because of its advantages such as high density, high strength, high toughness, and high impact toughness. And the weapon industry has become a major consumer of tungsten alloys. Well, do you know the specific applications of tungsten alloy in the weapon industry? More details, please visit: http://www.tungsten-alloy.com/en/alloy04.htm Tungsten alloy can be applied as the material of large-caliber kinetic energy armor-piercing projectile cores, machine gun armor-piercing discarding…
