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…
Tungsten
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…

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…
