What is tungsten Oxide?Tungsten dioxide has the molecular formula WO3 with a molecular mass of 231.85.
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 tungstentrioxide.
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 a concentrated sodium chloride solution 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 tungsten dioxide transparent insulation material
Smart homes make home life safer, more convenient and comfortable! 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 sunroom 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 a life of intelligence. 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 locking the door when you leave the house, set the scene to unmanned, shut off the power of the terminal blocks, and confirm home status anytime through the mobile application. 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, glass with a heat-insulating layer, hollow tempered and single-sided glass. The glass with the nano-tungsten coating has an infrared blockage rate of 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 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. 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. 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 as low as a few nanometers. This allows you to enjoy the "warm winter, and cool summer", without opening your air conditioner. In addition to its excellent insulation properties, this type of material is resistant to staining, has excellent privacy protection, and can be easily cleaned. . These materials include tungsten bronze as well as ITO, ATO FTO.
Tungsten-oxide insulation is not an "old 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 attention.
