The chemical formula of cesium tungsten bronze powder is generally CsxWO3, where the value of X is usually less than 0.33. This compound is composed of cesium, tungsten and oxygen, with non-stoichiometric ratio and special oxygen octahedral structure. This structure endows cesium tungsten bronze powder with a series of excellent properties, such as low resistivity, low temperature superconductivity and excellent optical properties. Its application in different fields shows its excellent performance and broad application prospects.
Transparent thermal insulation coatings and films
In the construction industry, cesium tungsten bronze powder is widely used to prepare transparent thermal insulation coatings. This kind of coating is applied to the glass exterior wall of the building, which does not affect the transparency of the glass, but also can effectively block infrared radiation, reduce indoor temperature and improve the energy efficiency of the building. Especially in hot summer, this coating can significantly reduce the use of air conditioners, save energy and reduce carbon emissions.
Automobile application
Transparent thermal insulation film made of cesium tungsten bronze powder is also widely used in the field of automobile film. This film can effectively reduce the temperature inside the car, so that drivers can enjoy a comfortable driving environment in hot summer. At the same time, because of its high transmittance, it will not affect the driver’s line of sight and ensure the driving safety.
Warm clothing
In the textile field, cesium tungsten bronze powder is used to make warm clothes. Cesium tungsten bronze particles are incorporated into the fibers of this kind of clothing, which can absorb and reflect the heat emitted by the human body and play a role in keeping warm. Especially in winter outdoor sports or cold areas, this kind of warm clothing can effectively resist the cold and improve the comfort of human body.
Military stealth suit
Cesium tungsten bronze powder can also be used to make military stealth clothing. This kind of clothing can absorb and scatter radar waves, reduce the probability of being detected by enemy radar and improve the survivability of soldiers. At the same time, its high transmittance ensures that the soldiers’ sight is not affected and the battle goes smoothly.
Laser marking and welding
In the field of laser marking and laser welding, cesium tungsten bronze powder is widely used because of its absorption characteristics of laser with specific wavelength. For example, in the marking process of metal parts, a clear and lasting mark can be formed on the surface of the parts by using the absorption of laser by cesium tungsten bronze powder. In the welding process, cesium tungsten bronze powder can absorb laser energy and convert it into heat energy, thus achieving accurate and efficient welding.
Photothermal diagnosis and treatment
In the medical field, cesium tungsten bronze powder is used for photothermal therapy. By injecting cesium tungsten bronze nanoparticles into the human body, the light energy is converted into heat energy to kill cancer cells by the irradiation of external light sources. This treatment method has the advantages of strong pertinence and less side effects, and provides a new means for tumor treatment.
infrared filter
In the manufacture of infrared filters, cesium tungsten bronze powder is applied because of its high refractive index and low extinction coefficient. This kind of filter can selectively transmit or reflect infrared radiation with a specific wavelength, and is widely used in infrared photography, night vision equipment and remote sensing detection.
With its unique optical, electrical and thermal properties, cesium tungsten bronze powder has shown broad application prospects in many fields. With the continuous progress of science and technology and in-depth research, it is believed that the application field of cesium tungsten bronze powder will be further expanded, bringing more convenience and innovation to human life.
