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, such as tungstic, sodium tungstate or calcium tungstate.
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 acids except hydrofluoric. It is soluble with hot sodium hydroxide solution, ammonia and hot concentrated sodium chloride to form soluble tantstate. If the temperature is greater than 650 deg C it can reduce by H2, but at 1000-1100 C it can reduce by C to get tungsten.

The application of transparent tungsten dioxide 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. 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 the 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? 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 a smart home scenario? ----After locking the front door, switch the smart home scenario to an unmanned mode, turn off the power of the terminal blocks, and check the status via the mobile 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. 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, glasses with heat-insulating films, hollow tempered and single-sided tempered glass. The glass coated with nano-tungsten dioxide has a 91% infrared blockage rate; the 91% ultraviolet blockage rate. 2. Low-e glass has an infrared blocking percentage of 62.8%, and UV blocking is at 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 a ultraviolet-blocking rate of 23.5%. 5. The infrared blocking percentage of single-sided glasses is 12.4%, and the ultraviolet blocking 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, a high UV-blocking rate is unhealthy. It is a well-known fact that solar radiation supplies energy to all of Earth's life activities. 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: Transparency is defined as the ability to transmit light. It also meets lighting requirements. High barrier for the near infrared. This reduces the energy consumed by blocking the sun's radiant heat.
Moreover, since it is an environmentally friendly heat-insulating water-based material, tungsten dioxide transparent heat insulating can be painted to a thickness as low as a few nanometers. This allows you to enjoy the "warm winter" and the "cool summer" effect without opening your air conditioner. 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 other functions. . 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 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.
