Violet tungsten oxide is an electrochromic material with excellent electrochromic properties that may be used to prepare a smart window. The research on electrochromic materials began in 1969. In that year, S.K. Deb first discovered the electrochromic properties of amorphous WO3 films and proposed the mechanism of “oxygen vacancy color center”. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html In the 1980s, American scientists proposed smart energy-saving windows based on electrochromic films. In 1994, the Germans used electrochromic technology to make the first…

Violet tungsten oxide can serve as a cathode electrochromic material – one of electrochromic materials. The other type is an anode electrochromic material. When the electrochromic material is at the cathode and is colored, it is called cathodic coloring, and its electrochemical reaction formula is: More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Moy + xA+ + xe- ? AxMOy (0≤x≤1) Where, MOy is a metal oxide (colorless), the metal has a higher oxidation state; A+ is an injected small positive ion such…

Violet tungsten oxide, like yellow tungsten oxide or tungsten trioxide, is an electrochromic material that may be used to produce electrochromic devices, such as smart windows. For electrochromic materials, experts have introduced the rich colors that the film has in the process of coloring. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts say that when different electrochromic materials are colored, the color of the film varies. For example, a tungsten trioxide film is colored from colorless to light blue to a final…

Violet tungsten oxide may be used to prepare an electrochromic film. The prepared electrochromic thin film and other components are sandwiched between common glasses to form an electrochromic window, that is, a smart window. Such smart window can dynamically control the transmittance of radiant energy in accordance with the changes of seasons and climate, thereby reducing the energy consumption indoors or in the car. And therefore, it is more and more widely applied to buildings and automobiles. More details, please…

Nano violet tungsten oxide coated glass is a heat insulating glass obtained by re-treating common glass by a glass coating method, wherein violet tungsten oxide is present on the glass substrate in the form of a thin coating layer. Such energy-saving glass is substantially transparent to visible light and is capable of shielding infrared radiation. Also, it is resistant to ultraviolet radiation. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Besides, the transparent coating layer of nano particle size tungsten oxide can also…

Violet tungsten oxide has photochromic properties so that it may be used to prepare a high performance photochromic thin film, that is, a heat insulating film, more specifically, a highly transparent thermal insulating film. According to the principle of photochromism, the thermal insulation film undergoes a color change reaction under the condition of light, and changes from colorless to blue, and has a good shielding effect on light intensity and ultraviolet light. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html In addition, experts…

Violet tungsten oxide, like tungsten trioxide, has good electrochromic properties, so it may be used to prepare an environmentally friendly electrochromic thin film for applying in smart windows for the purpose of thermal insulation, heat preservation and energy conservation. From a professional point of view, this is because the architectural glass applying with the tungsten oxide electrochromic film has the adjustability of light absorption and transmission under the electric field, which can effectively control the external heat radiation and internal…

Violet tungsten oxide nano powder, like yellow tungsten oxide nano powder or tungsten trioxide nano powder, is an oxide of tungsten, which has optical adjustment properties, so it may be used to produce a smart window. It is reported that a smart window consists of five layers of film on the glass, the structure of which is shown below. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Wherein, EC is an electrochromic material, which is a mixed conductor of electrons and ions. Under…

Yellow tungsten oxide is the most commonly used material for the preparation of an inorganic electrochromic film. And the obtained film can be used for producing an all-solid electrochromic glass, that is, the so-called smart glass, which is more and more widely applied in smart buildings to play the role of heat insulation in summer and heat preservation in winter. So, how to prepare WO3 electrochromic film? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Specifically, the tungsten powder of a particle size…
