Tungsten oxide is an electrochromic material. As you may have known, there are two types of electrochromic materials. They are inorganic electrochromic material and organic electrochromic material, and the tungsten oxide nano particles belong to the inorganic electrochromic material. And there is a process of electrochromism no matter what kind of electrochromic material it is. So, do you know to what the change in the color of electrochromic materials relates?

Tungsten trioxide is one of many kinds of inorganic electrochromic materials for preparing glass insulating coating. And WO3 is the typical representative of the most recently studied cathode electrochromic materials. But do you know why inorganic electrochromic materials are used as heat insulation coatings instead of organic electrochromic materials for exterior glasses of buildings?

Crystalline WO3 film may be used to produce a highly transparent energy-saving smart glass, which has the functions of heat insulation, ultraviolet shielding, anti-glare and explosion protection. So, do you know the energy-saving mechanism (or electrochromic mechanism) of such energy-saving glass?

Ammonium metatungstate powder can be used to prepare amorphous WO3 film and crystalline WO3 film. And the prepared films can be used to assemble an electrochromic glass - a new type of environmentally-friendly building energy-saving smart glass. Such heat insulation glass can achieve the goal of heat insulation, heat preservation, energy conservation and consumption reduction.

AMT, short for ammonium metatungstate, is one of the important raw materials for obtaining building energy-saving smart glass – a type of electrochromic glass. For example, some experts used ammonium metatungstate as raw material to prepare WO3 electrochromic film, and they tested the electrochromic properties of prepared WO3 film in the three-electrode system, using 0.5M H2SO4 solution as electrolyte by applying 1.5V voltage. The electrochromic performance of WO3 film heat treated at different temperatures is shown in the figure below.

Ammonium metatungstate may be applied for preparing energy-saving smart glass. But why? Because ammonium metatungstate nano powder can be used to prepare WO3 electrochromic thin films. And the tungsten trioxide film is an extremely important electrochromic layer material for producing electrochromic glass --- energy-saving smart glass.

WO3, more specifically, tungsten trioxide film, is an important electrochromic material for production of energy-saving smart glass. It is reported that tungsten oxide smart glass can reduce the building energy consumption to a certain extent, as it can realize the active dynamic adjustment process of indoor temperature, that is, to play the role of heat insulation and heat preservation.

Yellow tungsten oxide, also known as tungsten trioxide, may be used to produce a new type of energy-saving smart glass, which is environmentally-friendly for applying to the construction field, thereby playing an important role of thermal insulation, reducing building energy consumption, and achieving the purpose of environmental protection and energy conservation.

Tungsten trioxide is a cathode coloring material, and an electrochromic film composed of such electrochromic material is often used to assemble an electrochromic glass, that is, an energy-saving smart glass. So, the obtained glass will be smart with high energy saving effects.

Tungsten oxide is an inorganic electrochromic material that can be used to produce electrochromic glass with good energy-saving effects. As you may have known, electrochromic glass is considered to be the most promising energy-saving smart glass for large-scale commercial production.
