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.

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…

Tungsten oxide is a sensing material that has good sensitivity and selectivity to toxic gases such as NO2 gas, so it has good prospects in fabrication of NO2 gas sensors. Because the application of NO2 gas sensor is of great significance to environmental protection and human health, tungsten oxide-based gas sensor to NO2 gas has always been one of the research hotspots of researchers at home and abroad. More details, please visit: http://tungsten-oxide.com/index.html According to the literature, as early as…

As a photocatalytic material, WO3-TiO2 nanoparticles have been designed to obtain better catalytic performance as WO3 having encouraging physical and chemical properties is still not much effective alone. Such a photocatalytic material is promising to treat hazardous dyes in industrial wastewater by dyes degradation using photocatalysis with properties like reusability, low cost, complete degradation and ecofriendly. Some experts have prepared a novel photocatalyst WO3-TiO2 nanoparticles through a hydrothermal method by using cetyltrimethylammonium bromide (CTAB) as surfactant. More details, please visit:…
