Tungsten oxide powder for producing liquid electrochromic device is an electrochromic material, more specifically, an inorganic electrochromic material. And usually tungsten trioxide film rather than tungsten trioxide powder is used to assemble an electrochromic device. In fact, the electrochromic material can be further divided into a cathode electrochromic material and an anode electrochromic material in accordance with the coloring method. And tungsten oxide belongs to the cathode electrochromic material. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html As you may have known, inorganic…

Tungsten trioxide powder for liquid electrochromic device is a transition metal oxide with many special physical properties. This is because WO3 has a multi-phase transition and exhibits ferroelectricity. However, why is the chemical formula of tungsten trioxide usually written in the form of WO3-x rather than the form of WO3? The following are the answers from experts. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The crystal structure of the tungsten trioxide which strictly satisfies the stoichiometric ratio should be a distorted perovskite…

Tungsten trioxide for preparing liquid electrochromic device is actually used as an electrochromic material in the form of a tungsten trioxide thin film.
