Transparent thermal insulation film may be prepared by using blue tungsten oxide powder as raw material. And therefore, such material can be used in window glass of building and automobile where requiring high transparency and high ultrviolet shielding rate. While as you may have known blue tungsten oxide can be used in a rotary kiln in hydrogen reduction process to produce tungsten powder. The raw material required for the process is blue tungsten oxide, the FSSS particle size is (11-14)μm,…

Blue tungsten oxide powder for producing transparent thermal insulation film is formed by polymerizing crystal grains. However, some of the crystals of blue tungsten oxide powder are affected by the calcination atmosphere, so that they are also intercalated with violet tungsten oxide crystal grains or other crystal grains of tungsten oxides in addition to blue tungsten oxide crystal grains. After the blue tungsten oxide was ground and dispersed, it was observed by transmission electron microscopy. And it was found that,…

Blue tungsten oxide for transparent thermal insulation film’s morphology can be observed by conducting a transmission electron microscope experiment. In order to better observe the morphology of blue tungsten oxide crystals, the researchers selected two methods for preparing TEM samples, and compared the morphology images of samples prepared by the two methods. The following are discussing the two methods. 1.0 Grind the blue tungsten oxide agglomerate, disperse the agglomerates, and prepare a sample by using a carbon coating. The morphology…

Blue nano tungsten oxide may be applied for producing transparent thermal insulation film, which has a potential application with the development of preparing technology of thermal insulation film of blue tungsten oxide. So, some searchers observed the morphology of blue tungsten oxide grain by transmission electron microscopy. The following is the method for observing the morphology of powder crystals by directly cutting a film for transmission electron microscopy from micron-sized particles. The specific sample preparation steps are as follows: Step…

Dark blue nano tungsten oxide may be applied for preparing transparent thermal insulation film. And such heat-insulating film is more and more popular as nano grain size blue tungsten oxide has the characteristics of good ultraviolet blocking performance, near-infrared blocking effect and good visible light transmittance. Therefore, some scholars have observed the blue tungsten oxide powder by high-resolution transmission electron microscopy to observe the microstructure of the blue tungsten oxide crystal. From the observation results of high-resolution transmission electron microscopy,…

Blue tungsten oxide nanopowder may be used to prepare heat-insulating glass window film, which is widely used in many heat insulation fields, such as offices, exhibition halls, indoor pools, sunlight rooms, hotels, automobiles, and so on. The application of blue tungsten oxide powder in the field of heat insulation will be gradually promoted with the upgrading of future preparation technology of heat insulation material of blue tungsten oxide and the improvement of people’s living standards. Therefore, some researchers have observed…

Microstructure of blue tungsten oxide nano powder for preparing heat-insulating glass window film can be obtained by powder sample preparation technology and analysis of scanning electron microscope and transmission electron microscopy. As can be seen from the results, blue tungsten oxide particles are blue tungsten oxide aggregates which are formed by single crystal polymerization into polycrystalline particles and then composed of polycrystalline particles. Moreover, the phase composition of blue tungsten oxide powder is not uniform. Specifically, it can be divided…

Blue nano tungsten oxide may not only be used for the production of thermal insulation thin film which is widely used in fields requiring high heat insulation such as construction and automobiles, but also for preparing tungsten powder. As tungsten powder is widely used in the production of downstream tungsten products. Researchers have done a lot of experiments for better understanding the raw material — blue tungsten oxide. Some researchers adopt blue tungsten oxide powder to prepare medium grain size…

Dark blue nano tungsten oxide may be applied for producing thermal insulation thin film, which can also be used to prepare metal tungsten powder. As you may have known, tungsten oxide and reduction conditions determine the grain size of tungsten powder, and the grain size of tungsten powder largely determines the final grain size of tungsten carbide powder. Since tungstic acid and tungsten trioxide are replaced with blue tungsten oxide in the late 1980s and early 1990s, the quality and…

Blue tungsten oxide nano powder may be applied for producing thermal insulating glass material, which is widely used in fields requiring high heat insulation and high transparency, such as buildings, automobiles, and the like. Strictly speaking, the blue tungsten oxide powder mentioned above is not the same as the industrial blue tungsten oxide. Industrial blue tungsten oxide is a powdery mixture of various tungsten compounds, that is, it is an industrially unclear product whose chemical composition and physical structure are…
