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. Depending on 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 pale-yellow triclinic powder. Once the temperature reaches 740 deg C it changes into a tetragonal orange crystal. 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 soluble tungstate. 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 more 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, like a fire stove and winter, like 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 the smart home 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? 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? ----As soon as 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 smart room is a similar experience. Currently, Low-e is used in some sunrooms. 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 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 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 nano tungsten oxide coating has the best infrared blocking ability. Single-sided tempered glass with thermal film and nano tungsten oxide have the best ultraviolet blocking ability. Coated single-sided glass. Nevertheless, industry insiders say that because UV light has a bactericidal effect, and most people want to take pictures of the sun, a high UV block rate isn't healthy. It is well-known that solar radiation supplies 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: Transparency is defined as the ability to transmit light. It also meets the lighting requirements. High barrier for the near infrared. This reduces the energy consumed by blocking the radiant energy from the sun.
In addition, this transparent heat insulating tungsten-oxide material 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 having to open 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 a path towards sustainable development", these transparent insulation materials will receive more and greater attention.
