Nano blue tungsten oxide (BTO), as a type of raw material to prepare ceramic microsphere, has the characteristics of high temperature resistance, high visible light transmittance, high hardness, high thermal insulation, good photochromism, and uniform particle size. Thus, the obtained dingal ceramic particles inherit some of characteristics of BTO such as uniformity, dispersity, stability, good thermal insulation and transmittance of visible light. It was found that curves of XRD (X-ray diffraction) of blue tungsten oxide obtained by reducing different APT…

Blue tungsten oxide powder may be applied for manufacturing ceramic microsphere. And usage of obtained heat insulation ceramic nano particles is as follows: The first step: According to the requirements of visible light index and infrared shielding index, add appropriate weight of heat insulation masterbatch by calculated amount; The second step: Uniformly mix the heat-insulating masterbatch with ordinary plastic particles; The third step: produce the transparent heat insulation film in accordance with the biaxial stretching process, or produce the transparent…

Blue tungsten oxide may be applied for manufacturing ceramic microsphere, so that it will have the following advantages: 1. As a near-infrared shielding material, compared with the traditional ATO and ITO, this type of ceramic particles has high transmittance and higher near-infrared shielding rate. It can be used as the heat insulating film of window; 2. Good performance, high thermal stability, good dispersion, not easy to fade; 3. For the production of heat insulation film, haze <0.5%; 4. Does not…

Blue tungsten oxide nanopowder may be applied for preparing nano-ceramic color master, and therefore be applied to produce nano thermal insulation film. The obtained thermal insulation material has a visible light transmittance of more than 75%, an infrared light blocking rate of 95~99.9%, and an ultraviolet light blocking rate of 98% or more. Blue tungsten oxide may be prepared by using APT as raw material and calcing under hydrogen atmosphere. In order to prepare blue tungsten oxide with more cracks…

Nano blue tungsten oxide may be applied for producing nano-ceramic color master so that the color master will have excellent heat resistance, dispersity and weather resistance, and therefore can be used for manufacturing heat insulation films or heat insulation sheets. Particle Size Distribution and Loose Specific Weight of Blue Tungsten Oxide APT was used as raw material and calcined under H2 atmosphere to prepare blue tungsten oxide. By testing, it was found that the uniformity of blue tungsten oxide particles…

Blue tungsten oxide powder may be applied for the manufacturing of nano-ceramic color master, which has excellent characteristics such as water resistance, acid resistance and weather resistance. It has bright color. And it is easy to color. Effect of Calcining Temperature on Uniformity of Blue Tungsten Oxide Particles Blue tungsten oxide may be prepared by using ammonium paratungstate (APT) as raw material under H2 atmosphere and calcining temperature of 350-550°C. And obtained blue tungsten oxide was studied to find that…

Blue tungsten oxide may be applied to produce nano-ceramic color master. And the obtained dingal color master can be used in the field of transparent heat insulation film as it is easy to disperse in the product. Also, it does not affect the product quality, does not fade the product, and has excellent light resistance, high temperature resistance, wear resistance and weather resistance for long-term use. By studying the blue tungsten oxide powder, it was found that blue tungsten oxide…

Blue tungsten oxide nanopowder has special photochromic characteristic so that it may be applied for the production of thermal insulation masterbatch. And therefore, it may be used to produce heat insulation film with excellent heat insulation characteristic and stability. The stability here means that the dingal masterbatch will not react with the product when it is exposed to heat, light or high temperature for a long time. Oxygen Index and Color Change of Blue Tungsten Oxide Desiccant method may be…

Nano blue tungsten oxide may be applied for producing thermal insulation masterbatch so that it will have good heat insulation and light fastness. The both characteristics are attributed to the photochromic phenomenon of blue tungsten oxide (related to its specific structure), which solves the problem of fading and brittleness of irradiated products as they are exposed to near infrared rays and ultraviolet rays in sunlight. Effect of H2 Flow and Calcing Time on Morphology of Blue Tungsten Oxide At certain…

Blue tungsten oxide powder may be applied for manufacturing thermal insulation masterbatch so that it has excellent dispersity. In other words, the masterbatch will be uniformly dispersed in the product. And there will be no debasement of quality. Effect of Calcing Temperature on Morphology of Blue Tungsten Oxide Ammonium paratungstate (APT) was used as raw material to prepare blue tungsten oxide by calcing under hydrogen atmosphere. Calcination is performed at a temperature range of 350~550°C. And the prepared blue tungsten…
