Tungsten oxide nanoparticles may be used to produce a thermal insulation masterbatch, and then be used for preparing a building thermal insulation film or a car heat insulation film. The raw material nano particle size tungsten oxide can be prepared by a solvothermal method. So, what is the formation mechanism of solvothermal preparation of tungsten oxide? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html It is considered to be in accordance with the “smooth solution saturation precipitation” mechanism. In other words, in the…

Tungsten oxide nanoparticles may be used to produce a nano-ceramic dispersion solution, that is, a heat insulation dispersion solution, and thus be prepared into a thermal insulation film. As an environmentally-friendly building energy-saving material, tungsten oxide film has attracted more and more attention. Therefore, the preparation method of tungsten oxide nanoparticles, such as solvothermal method, has also received much attention from the industry. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html So why does solvothermal method attract widespread attention? The reasons are shown…

Tungsten oxide, mainly referred to as WO3-x, is a near infrared absorption material. Experts say that tungsten oxide nanopowder does not have the absorption of near-infrared light, so it needs to be reduced to WO3–x. So, how to reduce the tungsten oxide nano powder into WO3–x? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Taking nano particle size tungsten oxide as the original material, sintering in a reducing atmosphere of 350°C and 550°C [volume ratio V (H2): V (N2) = 1:9] for 1h,…

WO3 electrochromic film may be used to produce a smart window, in which the tungsten trioxide film is prepared from WO3 nanopowder. Specifically, experts say that the WO3 film can be combined with a counter electrode material such as a V2O5 film to form a smart window with better optical properties, and the reaction formula is: More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html LixWO3 + V2O5 ? WO3 + LixV2O5 Wherein, LixWO3 and V2O5 have absorption properties in the red light and…

WO3 electrochromic film is an important EC layer material for preparing electrochromic glass, that is, an electrochromic device. In general, in the actual preparation of electrochromic devices, electrochromic materials are required to have the characteristics of stable chemical properties, rapid color change response, high cycle life, reversible color change, highly sensitive color change, memory ding and good electrochemical redox reversibility. But why the light transmission rate of electrochromic glass decreases when it bleaches after repeated use? More details, please visit:…

Amorphous WO3 electrochromic film has broad application prospects in smart windows due to its excellent electrochromic properties. The amorphous phase tungsten trioxide film can be deposited on transparent conductive ITO glass by RF magnetron sputtering technology using WO3 ceramic target as raw material. Experts also studied the effect of sputtering power on the structure and optical properties of the prepared WO3 electrochromic thin film, and the electrochromic properties of film. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The results show that the…

Yellow tungsten oxide, also known as tungsten trioxide, is the core material for the preparation of an electrochromic device. And WO3 is present in the electrochromic layer of smart window in the form of a layer of electrochromic film. So, why the bleaching process of WO3 film takes less time than the coloring process? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts explained that this is because when the ion and electron double injection tungsten trioxide electrochromic thin film is limited by…

Nano WO3 can be used to produce an electrochromic film and then be used to assemble electrochromic devices, such as smart windows. Ultimately, these smart windows are applied in buildings for thermal insulation and energy conservation. Then, after completely bleaching, why is the light transmittance of the tungsten trioxide film slightly higher than the corresponding light transmittance when it is not colored? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html This is because when the film is colored by the external electric field,…

Mo-doped WO3 nanowire can be used to prepare an electrochromic film, which may be applied to smart buildings for high thermal insulation. Some experts have prepared a high-quality Mo-doped WO3 ultra-fine nanowire with a diameter of about 3nm which is oriented by nano-crystals by a low-temperature atmospheric method. These nanowires are uniformly dispersed in water to form stable nano-ink. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The experts sprayed the WO3 nanowires on the heated FTO conductive glass, and the oriented nanocrystals…

Nest-like WO3?0.33H2O may be used to prepare an electrochromic film and then be used to produce a smart window – an energy-saving window that provides the ding of thermal insulation, anti-glare and UV resistance. Specifically, some experts have prepared a nest-like hydrated tungsten trioxide electrochromic film on a FTO conductive substrate by a self-seeding hydrothermal method. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts said that the self-seeding hydrothermal method eliminates the dependence of the hydrothermal growth of tungsten trioxide film on…
