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. Depending on the amount of tungsten, the tungsten-trioxide salt can be divided into tungstic acids, sodium tungstates, calcium tungstates, ammonium tungstates, ammonium métatungstates, etc.
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 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 be further reduced 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. It makes life more artistic. 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 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? 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 door when you leave the house, set the scene to unmanned, shut 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 the intelligent sunroom is also similar. Low-e glass is now 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-insulating films, hollow tempered and single-sided glass. The tungsten nano-coated glass has an infrared blockage rate of 91%, and the ultraviolet blockage rate is also 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 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. Coated single-sided glass. According to insiders in the industry, a high UV-blocking rate is unhealthy because UV light can kill bacteria and most people will 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 best.

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 the energy consumed by blocking the sun's radiant heat.
As a transparent heat-insulating material made of tungsten dioxide, which is an environmentally friendly, water-based material, it only requires a thin layer of paint to achieve the desired effect. This allows you to enjoy 'warm winters and cool summers' without the need for air conditioning. In addition to its excellent insulation properties, this type of material is resistant to staining, has an anti-aging effect, and provides privacy protection. . 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 attention.
