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.
Tungsten Trioxide is a powder crystal of pale yellow triclinic. 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 hot concentrated sodium chloride to form soluble tantalate. If the temperature is greater than 650 deg C it can reduce by H2, but at 1000-1100 C it can be further reduced by C to get tungsten.

The application of transparent tungsten dioxide insulation material
Smart homes make home life safer, more convenient and comfortable! The smart home also saves energy and is environmentally friendly. It makes life more artistic. 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", and winter like "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 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 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 you lock the front door, turn the scene to unmanned, shut off all power supplies to the terminal blocks, and check the status via the mobile application at any time. It is not surprising that the author cannot stop sighing, smart homes make people feel more at ease.
The switch to the intelligent sunroom is also similar. Low-e glass is now used in some sunrooms. Researchers tested the blocking of ultraviolet and near infrared rays by glass coated with nano tungsten oxide coating and Low-e Glass, as well as glass with heat-insulating films, hollow-tempered glass, and single sided glass. Infrared blocking rates of the glass coated with nano-tungsten dioxide are 91%, and ultraviolet blocking rates are 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 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 most effective in blocking infrared light. Single-sided tempered glass with a thermal insulation film is the most effective for blocking ultraviolet light. Single sided glass that is coated. According to insiders in the industry, a high UV blockage rate is unhealthy because UV light is bactericidal, but normal people still need to take pictures of the sun. It is widely known that solar energy provides the necessary energy to sustain all human life. 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.
This transparent tungsten-oxide heat insulating film is an environmentally friendly, water-based material that can be painted to a thickness as low as a few nanometers. It will then give the impression of 'warm winter and cool Summer' without the need for air conditioning. This kind of insulation also offers excellent safety features (this type of glass will not produce a large amount of glass slag if it is broken), 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 "unsightly" 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.
