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.
Tungsten Trioxide is a powdery pale yellow triclinic crystal. 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 acid other than hydrofluoric. It is soluble with hot sodium hydroxide solution, ammonia and soluble tungstate. 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 makes home life safer, more comfortable and convenient. The smart home also saves energy and is environmentally friendly. It makes life more artistic. So, it's not surprising to see the smart sun room. The so-called "intelligence", one of them, is to break the room in summer like "fire stove", winterlike a 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 a smart home 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 would go out and come back halfway. Then, she'd remember something, did I lock my door? 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 the intelligent sunroom is also similar. Some sunrooms are now using Low-e glasses. Researchers tested the blocking of ultraviolet and near infrared rays by glass coated Low-e, glass with heat insulation film, hollow-tempered glass, and single-sided glasses. The tungsten nano-coated glass has an infrared blockage rate of 91%, and the ultraviolet blockage rate is 91%. 2. Low-e glass has an infrared blocking percentage of 62.8% and a UV blocking percentage of 56%. 3. The infrared blocking percentage of glass with heat-insulating films is 59%, while the ultraviolet blocking percentage is 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 a nano-tungsten coating is the most effective in blocking infrared light. Single-sided tempered glass with a thermal insulation film is the best for blocking ultraviolet light. Single sided coated glass. According to insiders in the industry, a high UV-blocking rate is unhealthy because UV light can kill bacteria and most people will need to take pictures of the sun. Solar radiation provides energy to all human activities on Earth. 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 the most effective.

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 sun's radiant energy.
The tungsten-oxide transparent heat insulating film is an environmentally friendly, water-based material that can be painted to a thickness as low as a few nanometers. This allows it to have the "warm winter" and the "cool summer" effect 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, anti glare, and anti radiation. . These materials include tungsten bronze as well as ITO, ATO FTO.
Tungsten-oxide insulation is not an "invisible technology" but rather a result of technological and scientific development. According to the author, in today's advocate of "energy conservation and emission reduction" as well as "taking on the path of sustainable growth", such transparent materials for insulation will receive more attention.
