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…

Dark blue nano tungsten oxide not only can be applied for the manufacturing of infrared thermal insulation nano material, but also be used to prepare medium grain size tungsten powder by cyclic redox process. As you may know, tungsten carbides may crack or break during use. Studies have shown that most of the places where tungsten carbides appear cracks and fractures are large-sized crystal grains. That is to say, in the production process, it is necessary to control the appearance…

Dark blue nano tungsten oxide, which may be applied for preparing infrared ultraviolet shielding material, is blue tungsten oxide with nano grain size. The shielding material obtained may be used in thermal insualting window glass. The phase composition of the nano grain size blue tungsten oxide is not a single phase. After being subjected to once oxidation and twice reduction, the blue tungsten oxide is transferred into the medium grain size tungsten powder with a particle diameter of 3~10μm, accounting…

Dark blue nano tungsten oxide may be applied for preparing transparent thermal insulation material. Certainly, the application of blue tungsten oxide is not limited to this. Blue tungsten oxide can also be used for the preparation of tungsten powder by cyclic redox process. Some scholars have studied the effect of cyclic redox of blue tungsten oxide on the particle size distribution of tungsten powder. They found that: 1.0 First reduction. Blue tungsten oxide is first reduced to tungsten powder in…

Dark blue nano tungsten oxide may be applied for preparing transparent thermal insulation nanopowder, which can be applied to a lot of heat insulation fields, such as baby room, sun room, elderly room, gym, indoor swimming pool, and botanical garden, etc. Moreover, with the advancement of science and technology and the improvement of living standards, people will definitely improve their own environment to enhance the comfort of the human body and thus improve the quality of life. Certainly, the blue…

Blue nano tungsten oxide for heat insulating window glass can be produced by calcining ultrapure ammonium paratungstate in argon. The particle size of the obtained blue tungsten oxide was detected to find that: the specific surface area of the blue tungsten oxide was 0.061m2/g, indicating that the particle size of the blue tungsten oxide was coarse. The particle size of the blue tungsten oxide is 85.38% between 9μm and 29μm, and 8.75% between 3μm and 9μm, and 5.87% between 29μm…

Blue nano tungsten oxide may not only be applied to prepare window heat insulation film for applying in building glass such as office buildings, hotels, villas, high-end apartments, exhibition halls, galleries and indoor swimming pools, but also to produce medium grain size tungsten powder by cyclic redox process. The so-called cyclic redox method is a recycling process in which blue tungsten oxide is reduced to tungsten powder, and then the tungsten powder is oxidized to tungsten trioxide and then reduced.…

Blue nano tungsten oxide may be used not only for preparing thermal insulating glass, but also for producing tungsten powder by cyclic redox process. The experimental materials and experimental equipment required to prepare tungsten powder by this method are as follows. 1.0 Experimental material. The ultrapure ammonium paratungstate (APT) used in the experiment was prepared by evaporative crystallization with a chemical formula of 5(NH4)2O?12WO3?5H2O. The content of WO3 in this ultrapure ammonium paratungstate was 89.06%, calcined at 750°C, and the…

Blue nano tungsten oxide may be applied for preparing heat insulation coating, and therefore be widely used in construction and automotive for high heat insulation and high visible light transmittance. Certainly, blue tungsten oxide powder has a wider range of uses, such as, preparation of tungsten powder. As tungsten powder is the raw material for many downstream tungsten products, manufacturers have also studied the preparation of tungsten powder in more depth. They reduce the blue tungsten oxide powder in hydrogen…

Blue nano tungsten oxide may be used to prepare thermal insulation coating. Such heat-insulating coating is widely used in fields such as buildings and automobiles that require high heat insulation and high transparency. Heat insulation scenes in the building sector include office buildings, shopping malls, hotels, showrooms, gyms, indoor swimming pools, and glass walls, etc. With the improvement of living standards, people’s demand for all aspects has increased, especially requirements for heat insulation in hot summer. Besides, such coating can…
