Dark blue nano tungsten oxide not only may be applied for the production of near-infrared shielding material, but also can be used to prepare AKS doped tungsten wire, i.e., tungsten wire doped with Al, Si and K. Researchers have done relative experiments. They used a regular type ammonium paratungstate (sample No. A) and a common type ammonium paratungstate (sample No. B) to produce blue tungsten oxide powder. Then, the obtained blue tungsten oxide is doped during the production of doped…

Dark blue nano tungsten oxide for thermal insulation paper can be produced by a mild H2 reduction method in a multi-tube furnace. Researchers have used two kinds of APT materials to study – ammonium paratungstate of regular crystal form and ammonium paratungstate of common crystal form. Comparing the 20 sets of specific surface area data produced by the two types APTs, they found that the specific surface area of the blue tungsten oxide powder produced by the regular type ammonium…

Dark blue nano tungsten oxide for thermal insulation film can be prepared by a mild H2 reduction method using a common type ammonium paratungstate or a regular type ammonium paratungstate as a raw material in a multi-tube furnace. The experimental results show that the particle size distribution of the blue tungsten oxide powder produced by the regular type ammonium paratungstate is better than that of common type ammonium paratungstate. Specifically, the ammonium paratungstate of common crystal form has an uneven…

Dark blue nano tungsten oxide for ceramic microsphere may be prepared by using the regular type ammonium paratungstate or the common type ammonium paratungstate as raw materials. Among them, the blue tungsten oxide powder obtained by using these two kinds of ammonium paratungstate has different ammonia contents. The results show that the ammonia content of blue tungsten oxide produced by regular type ammonium paratungstate is higher than that of blue tungsten oxide produced by common type ammonium paratungstate. The details…

Dark blue nano tungsten oxide may be applied for preparing thermal insulation masterbatch and be used to produce AKS-doped tungsten wire, i.e., tungsten wire doped with Al, Si and K elements. Moreover, studies have shown that the quality of blue tungsten oxide powder affects the performance of the AKS-doped tungsten wire. Therefore, it is necessary to have an in-depth understanding of ammonium paratungstate (APT) as a precursor in the preparation of blue tungsten oxide. At present, due to the pressure…

Dark blue nano tungsten oxide, which may be applied for preparing nano-ceramic color master, can be produced by using ammonium paratungstate (APT) as a precursor. Among them, some scholars believe that the quality of APT has a fundamental impact on the quality of blue tungsten oxide. Some scholars have also found through comparison experiments that the morphology and particle size of the raw material APT have strong inheritance to blue tungsten oxide powder obtained by reduction. Besides, some scholars have…

Dark blue nano tungsten oxide may not only be applied for preparing nano-ceramic dispersion solution, but also be used to produce AKS-doped tungsten wire (i.e., tungsten wire doped with Al, Si and K elements). This is because doping blue tungsten oxide has the following advantages. For example, the blue tungsten oxide powder has a large specific surface area and a large surface crack. Also, blue tungsten oxide has good ion exchange activity. Besides, there are a large amount of hydrogen…

Dark blue nano tungsten oxide may be applied for manufacturing thermal insulation dispersion, which is mainly used in heat insulation fields such as building window glasses and automotive window glasses. More important, blue tungsten oxide of heat insulation performance is a new potential in the future. Therefore, researchers have done lots of experiments to know this material. For example, they found that blue tungsten oxide powder can be prepared using ammonium paratungstate (APT) as a raw material. Among them, APT…

Dark blue nano tungsten oxide, which may be applied for producing thermal insulation dispersion liquid, is a new heat insulation material with potential market. So, the blue tungsten oxide is studied. Researchers have found that: the quality of blue tungsten oxide can be affected by the precursor ammonium paratungstate (APT). That is to say, blue tungsten oxide can inherit the structure, morphology and other properties of APT, so the quality of APT has a fundamental effect on the quality of…

Dark blue nano tungsten oxide for preparing near infrared shielding material is a new type of nano heat insulation material, which can shield most of IR and UV rays, especially for the near-infrared region with a wavelength of 800-1000nm and the ultraviolet region below 380nm. And the absorption and reflection effect is obvious. Such near-infrared absorbing material has a purity of more than 99.99% and a particle diameter of 50-100nm. It is prepared by high-temperature calcination. The tungsten oxide is…
