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. More details, please visit: http://www.tungsten-alloy.com/en/alloy04.htm Tungsten alloy applied for tactical missile can be…

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…

Tungsten alloy as a kind of medical radiation-proof material begin to be widely used because people gradually pay attention to the harm of radiation in medical devices for radiotherapy. It means that tungsten alloy having the characteristics of high melting point, high density, high temperature oxidation resistance, long service life and resistance to corrosion is promising as a radiation shielding material. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html According to the experts, the ability of metal materials to absorb X-rays and γ-rays…

In terms of X-ray shielding, tungsten alloy is non-toxic and non-polluting with high strength and good processing performance, compared to commonly used X-ray shielding material lead. And high density tungsten alloy shielding is widely used in nuclear medicine as collimator, container radioactive isotope, radiation source container, etc. Well, how about the X-ray shielding property of tungsten alloy? More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html In order to study the superiority and inferiority of the radiation shielding performance of tungsten alloy and lead,…
