Yellow tungsten oxide nanopowder may be applied for thermal insulation paper so that this type of heat-insulating paper has more excellent tear resistance, high temperature resistance, flexibility, electrical insulation property and mechanical processing properties. Certainly, due to the excellent photoelectric properties of yellow tungsten oxide, its application is wider, such as photochromic properties. And it was found that organic inducer such as n-propanol has a great impact on the properties of yellow tungsten oxide. N-propanol inducer has a great influence…

Nano yellow tungsten oxide may be applied for producing ceramic microsphere so that it has good heat resistance, nice weather resistance, and excellent dispersibility, etc. And thus, it may be used for producing heat insulating sheets or films. The visible light transmittance of the prepared heat insulating film is 50~75%, the infrared shielding rate is 90~99% and the ultraviolet shielding rate is 99%. Compared with traditional ATO and ITO, the near-infrared shielding material using yellow tungsten oxide as raw material…

Nano yellow tungsten oxide may be applied for nano-ceramic color master, which not only plays a role in dyeing, but also has the effect of enhancing the toughness of the ceramic. Certainly, yellow tungsten oxide may also be used for sewage treatment. And it works, for oily wastewater. Yellow tungsten oxide was subjected to oil water separation experiment and emulsion separation experiment. Oil water separation experiment: First, n-hexane and water were dyed with Sudan Tris and Methyl Blue, and an…

Nano yellow tungsten oxide may be used in nano-ceramic dispersion solution so that the ceramic dispersion plays a role of stabilizing, wetting, grinding and diluting effect in its application. Stabilizing Effect of Nano-ceramic Dispersion Solution In the absence of dispersion solution, the particles are mainly subjected to the following four forces in the water: gravity, buoyancy, particle/water interfacial tension, and interaction forces between particles, which will result in easy sedimentation of the particles and poor slurry stability. After the dispersion…

Nano yellow tungsten oxide is not only a type of near-infrared shielding material, but also a kind of wettability material. As a heat-insulating material, yellow tungsten oxide can be applied to building glass, car window glass, and the like. As a wettability material, the surface wetting properties need to be tested. It is worth to note that the study on the wettability of yellow tungsten oxide is still not deep enough, which greatly limits its practical application in industry. Hence,…

Nano yellow tungsten oxide may not only be applied for heat insulating window glass, but also for emulsion separation in water pollution treatment, which is developed with the development of the preparations of WO3. Hydrothermal synthesis of yellow tungsten oxide thin film and its application in emulsion separation will be introduced briefly below. First, 5mmol of sodium tungstate was dissolved in 20ml of deionized water and acidified to pH=2 with dilute hydrochloric acid (2M). Then, 14mmol of oxalic acid was…

Nano yellow tungsten oxide may be applied to window heat insulation film, which has excellent photochromic properties and can shield most of the ultraviolet rays and near-infrared rays. And therefore, it improves human comfort. Building glass contains window glass, glass door, skylight, and so on. Yellow tungsten oxide not only has high heat insulation and high visible light transmittance, but may be used to construct microstructures on various substrates and may be modified to regulate surface wettability. In this way,…

Nano yellow tungsten oxide may be used to prepare heat insulation masterbatch, which has the characteristics of high heat insulation, high transparency and low haze value. The yellow tungsten oxide nanopowder has a solid content of 5~10%, a dispersed particle size of less than 40nm, a visible light transmittance of 50~80%, an infrared ray shielding rate of 60~99% (varies with the addition ratio), and a finished product haze of less than 1. Yellow tungsten oxide also has surface wettability, and…

Nano yellow tungsten oxide may be used not only as a heat-insulating film in thermal insulating glass, but also as a catalyst or different roles in many other fields. For example, it can be applied in the fields of photochromism, electrochromism, visible light photocatalysis and gas sensing. Preparation of Tungsten Trioxide Film First, 5mmoL of sodium tungstate was dissolved in 5ml of deionized water and the solution was acidified with dilute hydrochloric acid (2M). Then, 5mmoL of oxalic acid was…

Nano yellow tungsten oxide is an important and common semiconductor, which has great application value in many fields. And therefore, it has attracted researchers’ great interest. For example, yellow tungsten oxide may be used in the preparation of heat insulation coating. It is worth to note that hydrate yellow tungsten oxide (WO3?H2O) is also a semiconductor. There are many processing methods for the production of various yellow tungsten oxide powders. These producing methods are chemical vapor deposition method, electrochemical deposition…
