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. According to the amount of tungsten, the tungsten-trioxide salt is classified as tungstic, sodium tungstate or calcium tungstate.
Tungsten Trioxide is a pale-yellow triclinic powder. 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 makes home life safer, more comfortable and 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 is to start at the source.

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? If you don’t go back to confirm, you won't make it through the day. But go back, and you'll be late to work! What about changing to a smart home scenario? ----After locking the front door, you can set the scene to unmanned, turn 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 smart room is a similar experience. Some sunrooms are now using Low-e glasses. Researchers tested the blocking of ultraviolet rays and near-infrared radiation by glass coated with nano-tungsten dioxide coating, Low e glass with heat-insulating films, hollow tempered glasses, and single-sided and tempered glass. The glass coated with tungsten dioxide nano-coating blocks infrared rays at 91%, while the UV blocking rate is also 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 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. Coated single-sided glass. However, industry insiders say that because UV light is bactericidal and most people want to take pictures of the sun, a high UV-blocking rate can be harmful. Solar radiation is known to provide energy for life 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 radiant sun's energy.
Moreover, because it is an environmentally friendly heat-insulating water-based material, tungsten dioxide transparent heat insulating can be painted to a thickness of a few millimeters and enjoy the "warm winter, cool summer" effect without opening the air conditioner. Moreover, this type of insulation material is very safe (if it breaks, the glass will not release a lot glass slag), has anti-aging properties, privacy protection and stain resistance. It also comes with 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 "black technology", it is the result of technological and scientific development. According to the author, in today's advocate of "energy conservation and emission reduction" as well as "taking a path towards sustainable development", these transparent insulation materials will receive more attention.
