The Boeing 787 "Dream Window" does not have a visor, but it can change the transmittance. What is similar to this is the tungsten oxide electrochromic film. The porthole of the Boeing 787 has no visor, but it can change the transparency! You only need to press the button, the porthole will become a "chameleon" until it is completely darkened! Of course, the captain can also dim directly from the cockpit when the night falls. In addition, because the color change process of this "electronic curtain" is gradual, you don't have to worry about the eyes being uncomfortable. What's more, when an unexpected power outage occurs, the portholes become completely transparent and comply with relevant aviation standards. At this point, some people may ask, "So, can you easily put the Boeing 787 'Magic Window' home?" This just seems impossible. In fact, only need to - tungsten oxide electrochromic film, this black technology can give you Boeing 787 enjoy!

Tungsten oxide (WO₃) is a kind of functional material, which has been widely studied in photochromic and gas-chromic fields. It has a wide range of applications in the field of photocatalysis and gas sensors. Through the study of bismuth doped tungsten oxide, it is found that the reflectivity of the material to near infrared is more than 95%.

In today's rapid development of the IT industry, the chip can be described as the brain of various data analysis, is the core! Now, for high-purity sputtering targets, the highest-end application area is the field of ultra-large-scale integrated circuit chip manufacturing, which is actually a field of semiconductor chips, and also occupies a large market share. Moreover, the market capacity of semiconductor chips in the future will be further enhanced with the continuous growth of semiconductor chip demand in the terminal consumer field such as automobiles.

Spherical tungsten powder is an important form of tungsten powder. Porous materials prepared from spherical tungsten powder have more uniform pores. In production, the gas permeability of the product can be controlled according to the process, so it will replace the conventional tungsten powder for making porous tungsten components, such as cathodes of high-power pulsed microwave tubes, electronic tantalum tungsten cathodes, gas distribution plates at high temperatures, and gas filtration materials.
