What is tungsten Oxide?Tungsten dioxide has the molecular formula WO3 with a weight of 2318.5.
It is a form of tungsticanhydride. Tungsten dioxide is not produced in industrial production. The tungsten-trioxide salts are classified according to their content in tungsten dioxide.
Tungsten Trioxide is a powder crystal of pale yellow triclinic. Once the temperature reaches 740 deg C it changes into an orange tetragonal crystalline. In air, it is stable, with a melting point of 1473 deg C and a boiling point higher than 1750.
Tungsten Trioxide is one of the most stable tungsten oxydes. It is not soluble in water or inorganic acids except hydrofluoric. It is soluble with hot sodium hydroxide solution, ammonia and hot concentrated sodium chloride to form soluble tantalate. If the temperature is greater than 650 degrees C, H2 can be used to reduce it. At 1000-1100 degrees C it can also be reduced with C.

The application of tungsten dioxide transparent insulation material
Smart homes make home life safer, more comfortable and more convenient. The smart home also saves energy and is environmentally friendly. So, it's not surprising to see the smart sunroom. One of these is the so-called "intelligence", which breaks the sun room into two parts: summer as "fire stove", and winter as "refrigerator". Transparent semiconductor materials like tungsten oxide transparent materials are a good way to make the sun room cool in summer and warm in winter. My opinion is that it's not necessary to install floor heating and air conditioning equipment. The best solution to heat insulation in the sunroom is to start at the roots.

This concept of smart homes has already permeated our minds and is being applied everywhere! Unfortunately, this author hasn't been able live an intelligent lifestyle. This led to the classic home scene: the author left the house every time. The result was that he forgot something, but remembered it halfway. Is your air conditioner turned off? You cannot survive the day if you do not go back to confirm. But go back, and you'll be late to work! What about changing to the smart home scenario? ----After you lock the front door, turn the scene to unmanned, shut off the power of the terminal blocks, and check the status from the app at any time. It is easy to use, and it makes people feel more at ease.
The switch to a smart room can also be compared. Low-e glass is now used in some sunrooms. Researchers tested the blocking of ultraviolet rays and near-infrared radiation by glass coated with nano tungsten oxide, Low-e, glass with heat insulation film, single-sided glass and glass coated with hollow tempered. They found that: Infrared blocking rates of the glass coated with nano-tungsten dioxide are 91%, and ultraviolet blocking rates are 91%. 2. Low-e glass has an infrared blocking percentage of 62.8%, and a UV blocking percentage of 56%. 3. Infrared rays are blocked 59% by the heat-insulating glass. UV rays are blocked 99.7%. 4. Hollow tempered glasses have an infrared-blocking rate of 34.2%, and an ultraviolet-blocking rate of 23.5%. 5. The infrared blocking percentage of single-sided glasses is 12.4%, and the ultraviolet blocking percentage is 13.5%.

As can be seen by the data, single-sided tempered glass with nano tungsten oxide coating has the best infrared blocking ability. Single-sided tempered glass with thermal film and nano tungsten oxide have the most effective ultraviolet blocking ability. Single sided glass that is coated. Industry insiders say that because UV light is bactericidal and most people want to take pictures of the sun, having a high UV-blocking rate can be harmful. It is widely known that solar energy provides the necessary energy to sustain all human life. The amount of infrared, ultraviolet, and other rays that are present in sunlight is important. In general, the scientifically-recommended permeability rate is around 10%. In terms of health and energy savings, using nano-tungsten oxide coated insulation glass is best.

It is clear that tungsten oxide is a transparent insulation material with two issues to solve urgently when building energy-saving windows: High transparency is defined as high transmittance of visible light and meeting lighting requirements. High barrier for the near infrared. This reduces energy consumption by blocking the radiant sun's energy.
This transparent tungsten-oxide heat insulating film is an environmentally friendly, water-based material that can be painted to a thickness as low as a few nanometers. It will then give the impression of "warm summer and cool winter" without the need for air conditioning. This kind of insulation also offers excellent safety features (if the glass breaks, there will be no glass slag), privacy protection, stain-resistance, self-cleaning capabilities, anti glare and anti radiation. . These materials include tungsten bronze as well as ITO, ATO FTO.
Tungsten-oxide insulation is not an "evil technology" but rather a result of technological and scientific development. According to the author, in today's advocacy for "energy conservation and emission reduction" as well as "taking the path towards sustainable development", these transparent insulation materials will receive more and greater attention.
