In recent years, studies have shown that polymer tungsten, also called tungsten rubber or tungsten resin, is the best material for the production of radiation protection clothing, radiation protection skirts and other medical radiation protection products. Well, do you know what are the advantages of polymer tungsten? Or what make tungsten rubber the preferred material for medical protection products?

Polymer tungsten, also known as tungsten resin and tungsten rubber, is a product made by combining various resin materials with tungsten powder particles in different proportions. Wherein, tungsten accounts for 60% of the product volume, but the weight accounts for more than 96% of the entire product; the resin material can be polypropylene, polybutene, polyurethane, thermoplastic materials, etc.

How to prepare WO3 hollow sphere? The experts have proposed a method for preparing WO3 hollow spheres at a lower temperature. This method can improve the utilization rate of WO3 catalyst to the light source, thereby reducing the cost.

Yellow tungsten oxide as a photocatalytic material can be used to produce hydrogen by photolysis of water. According to the experts, the photocatalytic material used for hydrogen production from photolysis of water should have good light corrosion resistance, electrolyte corrosion resistance, as well as a suitable forbidden band width.

Yellow tungsten oxide applied for photocatalytic degradation is known as tungsten trioxide or WO3, which has the characteristics of a small forbidden band width. And the absorption edge of WO3 extends into the visible light region. So, tungsten trioxide exhibits good photocatalytic degradation effect under visible light irradiation.

Nano yellow tungsten oxide, or nano tungsten trioxide or nano WO3, is a new type of nano material that can be applied for pollutant adsorption. The particle size of tungsten trioxide is very small, so it has a large specific surface area, which makes it have good physical adsorption and chemical adsorption properties. In addition, WO3 is an acidic oxide, and its surface has acidic properties, thereby it can effectively adsorb basic dyes and heavy metal ions.

WO3 hollow sphere is a non-toxic semiconductor material with narrow band gap (2.4-2.8eV), which can be used as a catalyst for the catalytic degradation of organic matter in sewage in visible light catalytic reaction. It has been reported that the photocatalytic performance of WO3 hollow spheres can be characterized by the degradation of Rhodamine B.

Yellow tungsten oxide hollow sphere is also called tungsten trioxide hollow sphere or WO3 hollow sphere, which has two surfaces - internal surface and external surface. And it is the two surfaces that allow WO3 to use light reflected into the interior multiple times through reflection, and therefore WO3 has unique applications, such as photocatalytic degradation of Rhodamine B solution.

It has been reported that yellow tungsten oxide film (It is more often known as tungsten trioxide film or WO3 film.) may be used as the basic material for package security label. This is mainly a package security label made by combining the characteristics of WO3 film under ultraviolet (sunlight) radiation with other technologies.

Yellow tungsten oxide, which is also known as tungsten trioxide or WO3, has huge application prospects in smart windows, photocatalysts, gas sensors, etc., so its preparation methods have always been one of the key research directions of researchers. There are many methods for preparing tungsten trioxide, such as hydrothermal method and template method. Here is a preparation method of tungsten trioxide.
