Tungsten disulfide (WS2) is known as the best dry film lubricant, and is regarded as the best way to solve surface wear. Well, do you know – what are the properties of WS2? More details, please visit: http://tungsten-disulfide.com/index.html Physical properties of tungsten disulfide: Gray fine crystals or powder with metallic luster. Hexagonal (β-WS2) or orthorhombic crystal system (α-WS2). It has a layered structure, wherein, each W ion is surrounded by a cluster of S atoms arranged in a triangular prism…

Nano tungsten disulfide, or nano WS2, is well-known as one of the most lubricious substance in world. It is a dry/solid lubricant powder with a low friction coefficient and a large compressive strength. Purity of nano tungsten disulfide is higher than 99.9%, W = 73.5-74.3 wt%. More details, please visit: http://tungsten-disulfide.com/index.html Nano tungsten disulfide has unmatched dry lubricity than any other substance, including graphite or molybdenum disulfide (MoS2), so it is widely used as a dry lubricant in aerospace, aviation,…

Tungsten alloy kinetic energy penetrator refers to a kinetic energy penetrator that adopts tungsten heavy alloy or a new type of tungsten alloy composite material as the core material of the armor-piercing projectile. The reason why tungsten alloy can serve as the core material of the kinetic energy armor-piercing projectile is that tungsten alloy has many good properties, such as high density, high melting point, high strength, good machinability, and extremely stable dynamic plastic deformation performance.

According to the literature, the new tungsten alloy ball can be used as a good high-speed impact body for cluster bomb (a canister of small individual bombs that is dropped from an aircraft) to improve its killing power. In the past, most of the cluster bombs used steel balls and lead balls, which have main disadvantage – lighter in weight, so that they are less powerful for weapons. More details, please visit: http://www.tungsten-alloy.com/en/alloy04.htm In order to further improve the killing…

According to the literature, the researchers have developed a new tungsten tin alloy shotgun bullet core. The bullet core of shotgun is mainly composed of some tungsten tin alloy balls. The preparation process of such tungsten tin alloy balls includes three steps, namely powder mixing, “V” mixer mixing, and die casting. More details, please visit: http://www.tungsten-alloy.com/en/alloy04.htm This new tungsten tin alloy shotgun bullet core has higher density than tungsten alloy shotgun bullet core to reach the ideal range. The density…

Tungsten alloy bullet, which is also known as tungsten alloy pellet, is a new lead-free bullet. It is an environmentally friendly bullet or a green bullet that made of high quality tungsten heavy alloy. Tungsten alloy bullets have low toxicity and will not cause serious pollution to the environment. What is more important is that the accuracy, lethality and penetration of tungsten alloy pellets are better than lead bullets. More details, please visit: http://www.tungsten-alloy.com/en/alloy04.htm Lead is always the main raw…

WO3 is the optimal sensing material for producing O3 gas sensor by detecting changes in surface conductance after tungsten trioxide film on sensor contacts the measured gas – O3. As we all know, O3 has been widely used in disinfection and sterilization, sewage treatment and other aspects. More details, please visit: http://tungsten-oxide.com/index.html However, excess O3 in the air (when the relative volume fraction exceeds 10^-7) will do harm to the human body and also damage other materials such as clothing…

WO3, a n-type oxide semiconductor, is regarded as the best sensing material for fabrication of H2S gas sensor to realize the monitoring and detection of H2S gas. You know, H2S gas is an air pollutant, which not only seriously threatens human health, but also affects industrial production. In industry, the maximum allowable mass concentration of H2S in air is 0.01 mg/L. So, there is an urgent need to develop a H2S gas component. More details, please visit: http://tungsten-oxide.com/index.html WO3-based H2S…

WO3 thin film is regarded as the best sensing material for the fabrication of sensitive and selective NO2 gas sensor. Some experts have fabricated NO2 gas sensor using WO3 thin films grown directly on to a soda-lime glass substrate without assistance of any seed layer by a simple and a facile hydrothermal technique. More details, please visit: http://tungsten-oxide.com/index.html According to the experts, the deposition of nanostructured WO3 thin films without assistance of any seed layer on the glass substrate was…

WO3 has excellent sensitivity and fast response speed to NH3 – colorless gas with strong pungent odor, so it is often made into a semiconducting gas sensor for NH3 detection. And therefore, WO3-based NH3 gas sensor has become one of the key research projects of scholars at home and abroad. More details, please visit: http://tungsten-oxide.com/index.html According to reports, as early as 1992, researchers have studied the sensitivity of doped tungsten trioxide films to NH3 in the air. So far, there…
