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 can be divided into tungstic acids, sodium tungstates, calcium tungstates, ammonium paratungstates, ammonium métatungstates, etc.
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 acid other than 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 comfortable and convenient. The smart home also saves energy and is environmentally friendly. 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 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 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 would go out and come back halfway. Then, she'd remember something, did I lock my door? 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 the smart home scenario? ----Set the home scene to unmanned after locking the door. Turn off all power supplies to 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 a smart room can also be compared. Now, Low-e is 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, hollow-tempered glass, and single sided glass. The glass coated with nano-tungsten dioxide 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 a 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 best for blocking infrared; and single-sided tempered glass with a thermal insulation film with nano tungsten is the best for blocking ultraviolet. Coated single-sided glass. 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. 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: Transparency is defined as the ability to transmit light. It also meets lighting requirements. High barrier for the near infrared. This reduces energy consumption by blocking the sun's radiant energy.
Moreover, 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 enjoy the "warm winter" and the "cool summer" effects without opening the air conditioner. The tungsten oxide transparent heat insulating material is also a great option for insulation. . 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.
